A dental technician is a member of the dental team who, upon prescription from a dental clinician, constructs custom-made restorative and dental appliances. [1] [2]

Contents

There are four major disciplines within dental technology. These are fixed prosthesis including crowns, bridges and implants; removable prosthesis, including dentures and removable partial dentures; maxillofacial prosthesis, including ocular prosthesis and craniofacial prosthesis; and orthodontics and auxiliaries, including orthodontic appliances and mouthguards. [3]

The dentist communicates with the dental technician with prescriptions, drawings, and measurements taken from the patient. The most important aspect of this is a dental impression into which the technician flows a gypsum dental stone to create a replica of the patient's anatomy known as a dental cast. A technician can then use this cast for the construction of custom appliances. [4]

Fixed restorations

A fixed dental restoration is an appliance designed to replace a tooth or teeth that may have been lost or damaged by injury, caries or other oral diseases. These restorations are distinguished from other restorations by the fact that once they have been placed by a dentist the patient can not remove them. [5] Such restorations include crowns, bridges, veneers, fixed implant restorations, pivot teeth, inlays and onlays. [6] [7]

Removable restorations

Removable restorations are dental appliances to replace one or more teeth that have been completely lost. These restorations ideally remain stable in normal function but can be removed by the patient for cleaning and at night. Removable restorations are either retained by the patients soft tissue as in full dentures, [8] anchored and stabilized by other teeth as with partial dentures and overdentures [9] or on implant attachments as with implant-retained overdentures and partial dentures.

Orthodontics

Orthodontic technicians make removable orthodontic appliances with wires, springs, and screws on prescription from an orthodontist to either move teeth to form a more harmonious occlusion and aesthetic appearance of teeth or to maintain the position of previously moved teeth.

Specialization

Training to become a dental technician requires a combination of academic study as well as experience gained from working on the job. Therefore, regardless of the country that they are from, after becoming a qualified technician (so long as the title of “dental technician” exists there) one has finished their studies, but not their training since these crafts take years of experience to master.

Depending on the position held by the dental technician, their specific title could differ as well (“ceramicist”, “polisher”, “orthodontist”, etc.). In fact, due to the complexity of the work that is carried out by dental technicians, a professional generally specializes in one field of dental prosthesis. Since the range of devices to design and create is extremely varied, it would be impossible to make all of them with the same set of skills, further, to completely master any technique may require years of experience.

In general, the first step a dental technician makes is to “master the plaster”, meaning that they first start in the part of the lab where dental impressions are made, cutting models, and mounting articulators. The dental technician may acquire the ability to carry out various and disparate tasks in the lab, being able to even execute most steps in the production of various prosthetics, such as removable partial dentures, complete and partially made of resin, and orthodontic devices (including braces and retainers). Nevertheless, as mentioned previously, dental technicians need to specialize; in fact, there are many specific dental labs that exist for each and every type of prosthesis.

The distinct specialties are described below:

Polisher

A polisher is a dental technician who dedicates themselves to the setup of teeth, either in making removable prosthetics made of resin or metal, molding the neck of the tooth, or loading the resin. Within their profession, they can also be referred to as a waxer.

Metalworker

A metalworker is a dental technician who is in charge of casting dental rods, which means they mold the metal and obtain the metallic frames for fixed prostheses, similar to the removable prosthetics made of resin. They are also in charge of processing and reworking said metal. These professionals can also be in charge of designing the wax patterns of removable metallic prostheses, such as the copings of crowns and fixed bridges. Among other things, this depends on the dental technician and the lab in which they work.

Prosthetic orthodontists

It is very common to differentiate a prosthetist who works with removable orthodontics, as it is normal to find professionals who specialize in this field. Removable equipment consists of a variety of different devices, each with specific naming and characteristics. Prosthetic orthodontists should be both agile and precise when handling different pliers and manipulating wires.

Ceramicist

A ceramicist is a dental physician who has specialized in the final stage of making fixed prosthetics, which consists of the assembly of ceramic on different prosthetic structures such as: bridges, crowns, prosthetic implants or prosthetic attachments. This technique is complex and requires artistic talent, so much so that dental technicians can achieve different levels of ability, developing their creativity to a greater or lesser extent to give your teeth the most natural look possible. As such, ceramicists are often considered valued professionals.

Products

Dental technicians predominantly make dentures, or similarly, create artificial parts that are intended to basically replace the natural, missing teeth of the patient.

Therefore, dental technicians make complete resin prosthetics (commonly called dentures), partial prosthetics (being metallic or made of resin), bridges and crowns of any type (fixed prosthetics, also called dental implants), and mixed prosthetic devices. Further, dental technicians also make all removable orthodontic devices (removable orthodontics), dental splints, individual compression trays, temporary resin prosthetics, bite plates, as well as study models. Dental technicians are also in charge of making composites (the repairing of prosthetics in case they break) and relining (the readjustment of prosthetics when they are too big or become flimsy in the mouth due to the reabsorption of alveolar bone over time). All of these, concerning the plaster models or instructor models, being a crime that acts on the patient's mouth.

In every country that legally regulates the profession of dental technicians, the prosthetist is the only professional trained and authorized by law to make the previously mentioned products.

By law, dental technicians can never, even if there is a medical prescription, take impressions- the client of the prosthetists is legally the dentist, and it is considered an intrusive crime by the Penal Code[ which? ] if a prosthetist touches the mouth of the patient.

Objectives

The goal of a dental technician can be summarized as restoring functionality, health, and aesthetic of the mouth.

The only goal of a prosthetist is not just to create a prosthetic, but rather to restore the loss of functionality of a patient’s mouth, from mastication and swallowing to speaking and correct phonetics. Through the work of a prosthetist, a patient’s oral health, mechanical function, hygiene, and comfort are revamped, including the aesthetic of the mouth and face.

This objective is a combined effort between clinical and lab members, an effort that is, in part, coordinated and achieved by the dentist and the prosthetist. That said, the only one in charge of the creation of prosthetics is the prosthetist, being a handcrafted, personalized, unique item designed in the dental lab.

Orthodontics is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, as well as misaligned bite patterns. It may also address the modification of facial growth, known as dentofacial orthopedics.

<span class="mw-page-title-main">Retainer (orthodontics)</span> Device to hold teeth in position

Orthodontic retainers are custom-made devices, usually made of wires or clear plastic, that hold teeth in position after surgery or any method of realigning teeth. Once a phase of orthodontic treatment has been completed to straighten teeth, there remains a lifelong risk of relapse due to a number of factors: recoil of periodontal fibres, pressure from surrounding soft tissues, the occlusion and patient’s continued growth and development. By using retainers to hold the teeth in their new position for a length of time, the surrounding periodontal fibres adapt to changes in the bone which can help minimize any changes to the final tooth position after the completion of orthodontic treatment. Retainers may also be used to treat overjets.

<span class="mw-page-title-main">Dentures</span> Prosthetic devices constructed to replace missing teeth

Dentures are prosthetic devices constructed to replace missing teeth, supported by the surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable. However, there are many denture designs, some of which rely on bonding or clasping onto teeth or dental implants. There are two main categories of dentures, the distinction being whether they fit onto the mandibular arch or on the maxillary arch.

<span class="mw-page-title-main">Dental braces</span> Form of orthodontics

Dental braces are devices used in orthodontics that align and straighten teeth and help position them with regard to a person's bite, while also aiming to improve dental health. They are often used to correct underbites, as well as malocclusions, overbites, open bites, gaps, deep bites, cross bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws.

Cosmetic dentistry is generally used to refer to any dental work that improves the appearance of teeth, gums and/or bite. It primarily focuses on improvement in dental aesthetics in color, position, shape, size, alignment and overall smile appearance. Many dentists refer to themselves as "cosmetic dentists" regardless of their specific education, specialty, training, and experience in this field. This has been considered unethical with a predominant objective of marketing to patients. The American Dental Association does not recognize cosmetic dentistry as a formal specialty area of dentistry. However, there are still dentists that promote themselves as cosmetic dentists.

<span class="mw-page-title-main">Dental implant</span> Surgical component that interfaces with the bone of the jaw

A dental implant is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biological process called osseointegration, in which materials such as titanium or zirconia form an intimate bond to the bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic is attached to the implant or an abutment is placed which will hold a dental prosthetic/crown.

Prosthodontics, also known as dental prosthetics or prosthetic dentistry, is the area of dentistry that focuses on dental prostheses. It is one of 12 dental specialties recognized by the American Dental Association (ADA), Royal College of Surgeons of England, Royal College of Surgeons of Edinburgh, Royal College of Surgeons of Ireland, Royal College of Surgeons of Glasgow, Royal College of Dentists of Canada, and Royal Australasian College of Dental Surgeons. The ADA defines it as "the dental specialty pertaining to the diagnosis, treatment planning, rehabilitation and maintenance of the oral function, comfort, appearance and health of patients with clinical conditions associated with missing or deficient teeth or oral and maxillofacial tissues using biocompatible substitutes."

A dental emergency is an issue involving the teeth and supporting tissues that are of high importance to be treated by the relevant professional. Dental emergencies do not always involve pain, although this is a common signal that something needs to be looked at. Pain can originate from the tooth, surrounding tissues or can have the sensation of originating in the teeth but be caused by an independent source. Depending on the type of pain experienced an experienced clinician can determine the likely cause and can treat the issue as each tissue type gives different messages in a dental emergency.

<span class="mw-page-title-main">Palatal lift prosthesis</span>

A palatal lift prosthesis is a prosthesis that addresses a condition referred to as palatopharyngeal incompetence. Palatopharyngeal incompetence broadly refers to a muscular inability to sufficiently close the port between the nasopharynx and oropharynx during speech and/or swallowing. An inability to adequately close the palatopharyngeal port during speech results in hypernasalance that, depending upon its severity, can render speakers difficult to understand or unintelligible. The potential for compromised intelligibility secondary to hypernasalance is underscored when consideration is given to the fact that only three English language phonemes – /m/, /n/, and /ng/ – are pronounced with an open palatopharyngeal port. Furthermore, an impaired ability to effect a closure of the palatopharyngeal port while swallowing can result in the nasopharyngeal regurgitation of liquid or solid boluses.

A dental auxiliary is any oral health practitioner other than a dentist & dental hygienist, including the supporting team assisting in dental treatment. They include dental assistants, dental therapists and oral health therapists, dental technologists, and orthodontic auxiliaries. The role of dental auxiliaries is usually set out in regional dental regulations, defining the treatment that can be performed.

Orthodontic technology is a specialty of dental technology that is concerned with the design and fabrication of dental appliances for the treatment of malocclusions, which may be a result of tooth irregularity, disproportionate jaw relationships, or both.

<span class="mw-page-title-main">Denturist</span>

A denturist in the United States and Canada, clinical dental technologist in the United Kingdom and Ireland, dental prosthetist in Australia, or a clinical dental technician in New Zealand is a member of the oral health care team and role as primary oral health care provider who provides an oral health examination, planning treatment, takes impressions of the surrounding oral tissues, constructs and delivers removable oral prosthesis treatment directly to the patient.

<span class="mw-page-title-main">Dental laboratory</span>

Dental laboratories manufacture or customize a variety of products to assist in the provision of oral health care by a licensed dentist. These products include crowns, bridges, dentures and other dental products. Dental lab technicians follow a prescription from a licensed dentist when manufacturing these items, which include prosthetic devices and therapeutic devices. The FDA regulates these products as medical devices and they are therefore subject to FDA's good manufacturing practice ("GMP") and quality system ("QS") requirements. In most cases, however, they are exempt from manufacturer registration requirements. Some of the most common restorations manufactured include crowns, bridges, dentures, and dental implants. Dental implants is one of the most advanced dental technologies in the field of dentistry.

<span class="mw-page-title-main">CAD/CAM dentistry</span> Computer-aided design and manufacturing of dental prostheses

CAD/CAM dentistry is a field of dentistry and prosthodontics using CAD/CAM to improve the design and creation of dental restorations, especially dental prostheses, including crowns, crown lays, veneers, inlays and onlays, fixed dental prostheses (bridges), dental implant supported restorations, dentures, and orthodontic appliances. CAD/CAM technology allows the delivery of a well-fitting, aesthetic, and a durable prostheses for the patient. CAD/CAM complements earlier technologies used for these purposes by any combination of increasing the speed of design and creation; increasing the convenience or simplicity of the design, creation, and insertion processes; and making possible restorations and appliances that otherwise would have been infeasible. Other goals include reducing unit cost and making affordable restorations and appliances that otherwise would have been prohibitively expensive. However, to date, chairside CAD/CAM often involves extra time on the part of the dentist, and the fee is often at least two times higher than for conventional restorative treatments using lab services.

<span class="mw-page-title-main">Dental prosthesis</span> Intraoral device for reconstructing missing teeth

A dental prosthesis is an intraoral prosthesis used to restore (reconstruct) intraoral defects such as missing teeth, missing parts of teeth, and missing soft or hard structures of the jaw and palate. Prosthodontics is the dental specialty that focuses on dental prostheses. Such prostheses are used to rehabilitate mastication (chewing), improve aesthetics, and aid speech. A dental prosthesis may be held in place by connecting to teeth or dental implants, by suction, or by being held passively by surrounding muscles. Like other types of prostheses, they can either be fixed permanently or removable; fixed prosthodontics and removable dentures are made in many variations. Permanently fixed dental prostheses use dental adhesive or screws, to attach to teeth or dental implants. Removal prostheses may use friction against parallel hard surfaces and undercuts of adjacent teeth or dental implants, suction using the mucous retention, and by exploiting the surrounding muscles and anatomical contours of the jaw to passively hold in place.

In dentistry, SMK, short for System kompozytowy most(in Polish), is an adhesive restorative prosthodontic technique, developed in Poland during the 1990s. Using the SMK method, a prosthetic tooth is constructed and fitted without damage to the neighbouring teeth.

<span class="mw-page-title-main">Anchorage (orthodontics)</span> Way of resisting tooth movement in orthodontics

Anchorage in orthodontics is defined as a way of resisting movement of a tooth or number of teeth by using different techniques. Anchorage is an important consideration in the field of orthodontics as this is a concept that is used frequently when correcting malocclusions. Unplanned or unwanted tooth movement can have dire consequences in a treatment plan, and therefore using anchorage stop a certain tooth movement becomes important. Anchorage can be used from many different sources such as teeth, bone, implants or extra-orally.

A complete denture is a removable appliance used when all teeth within a jaw have been lost and need to be prosthetically replaced. In contrast to a partial denture, a complete denture is constructed when there are no more teeth left in an arch, hence it is an exclusively tissue-supported prosthesis. A complete denture can be opposed by natural dentition, a partial or complete denture, fixed appliances or, sometimes, soft tissues.

<span class="mw-page-title-main">Overdenture</span> Removable dental prosthesis

Overdenture is any removable dental prosthesis that covers and rests on one or more remaining natural teeth, the roots of natural teeth, and/or dental implants. It is one of the most practical measures used in preventive dentistry. Overdentures can be either tooth supported or implant supported. It is found to help in the preservation of alveolar bone and delay the process of complete edentulism.
