[Repair of tooth wear; restorative-prosthetic aspects].

Tooth wear is considered to be the third major threat to dental health in the industrialized parts of the world next to caries and periodontal disease. Bruxism can be a cause for excessive tooth wear. Thanks to the successes in the prevention and early treatment of the infectious dental diseases, dentitions last longer as result of which tooth wear is becoming more and more of a problem in the preservation of a physiologic dentition throughout live. Furthermore there seems to be an increasing tendency for the occurrence of severe tooth wear at very early ages. Early recognition of possible contributing factors for tooth wear by the dental team is of utmost importance to enhance success in treating the problem. Prevention of ongoing damage to the remaining tooth structure must be the starting point of every treatment plan. Repair of tooth wear is in many cases a challenge from a restorative/prosthetic perspective: esthetic and phonetic aspects play an important role along with the restorative and prosthetic choices as well as functional considerations the clinician has to deal with.

Prevalence in the Dutch adult population and a meta-analysis of signs and symptoms of temporomandibular disorder.

A nationwide survey of oral conditions, treatment needs, and attitudes toward dental health care in Dutch adults was carried out in 1986. One of the aims of the study was to assess the prevalence of signs and symptoms of temporomandibular disorder (TMD). A sample of 6577 persons (from 15 to 74 yr of age), stratified for gender, age, region, and socio-economic status, was contacted. Of this sample, 4496 persons participated in the behavioral part of the study, of whom 3526 were examined clinically. The TMD prevalence was based on (1) perceived signs and symptoms of TMD and (2) clinical examination of joint sounds, deviation, and pain on mandibular movements. A total of 21.5% of the Dutch adult population perceived some dysfunction, and 44.4% showed clinically assessed signs and symptoms of TMD. In nearly all age groups, the signs and symptoms of TMD appeared more in women than in men. Agreement between the results of the clinical examination and the anamnestic dysfunction index was significant (p < 0.0001); however, the Pearson's correlation coefficient was low (r = 0.29). The odds-value (risk-ratio) that subjects who perceived signs and symptoms of TMD would present with clinically assessed signs and symptoms of TMD was 2.3. The results of the survey were compared with results of a meta-analysis performed on 51 TMD prevalence studies. The analysis revealed (1) a perceived dysfunction rate of 30% and (2) a clinically assessed dysfunction of 44%, both based on compound samples of, respectively, over 15,000 (23 studies) and over 16,000 (22 studies) randomly selected subjects.

Distal extension removable partial dentures supported by implants and residual teeth: considerations and case reports.

The traditional treatment for an edentulous maxilla opposed by a partially edentulous mandible with a complete denture and a distal extension removable partial denture is fundamentally inadequate. Continuing resorption of alveolar bone under the denture base of the removable partial denture causes changes in the occlusal plane. Consequently, overloading of the anterior maxillary region occurs, usually leading to increased bone resorption in the anterior maxillary ridge. Placement of implants beneath the distal extension denture base of the removable partial denture can result in a stable and durable occlusion. Two patients in whom the use of implants combined with a cast metal removable partial denture provided occlusal stability and improved functional comfort are presented.

Demand and need for treatment of craniomandibular dysfunction in the Dutch adult population.

A nationwide survey of oral conditions, treatment needs, and attitudes toward dental health care in Dutch adults was carried out in 1986. One of the aims of the study was to investigate the perceived need and demand for treatment of craniomandibular dysfunction (CMD). A sample of 6577 persons (15-74 yrs of age), stratified for gender, age, region, and socio-economic status, was contacted. Of this sample, 4496 persons participated in the behavioral part of the study, of which 3526 were examined clinically. The CMD-treatment demand was based on (1) CMD complaints in the past, (2) CMD complaints at present, and (3) an anticipated increase of the present complaints. CMD was both anamnestically and clinically assessed, independently by different examiners. A total of 21.5% of the Dutch adult population reported dysfunction, but 85% of these perceived no need for treatment. With most of the remaining 15% either seeking or intending to seek treatment (or having had it before), a figure of 3.1% can be used to summarize the actual level of treatment need for CMD in the Dutch adult population.

Management of an anterior defect with a removable partial denture supported by implants and residual teeth: a case report.

The treatment of a patient with a major defect in the anterior region of the mandible is described. A large part of the anterior dental arch and underlying mandibular bone was involved in the defect. A removable partial denture supported by implants as well as residual teeth was used to restore the defect. Compared with a traditional removable partial denture, which was used by the patient for several years as an interim prosthesis, the application of implants resulted in improved functional comfort and stability.

Cingulum bar as a major connector for mandibular removable partial dentures.

In the international literature and textbooks, the cingulum bar as a mandibular major connector is often neglected. It is a viable alternative to a lingual bar where the distance between the marginal gingivae and the mucolingual fold is restricted. It also provides indirect retention and thereby eliminates the need for a conventional indirect retainer. Patient comfort with an RPD with a cingulum bar seems acceptable because the connector forms one unit with the anterior teeth. The replacement of a lost natural anterior tooth with a denture tooth is not difficult. The metal bulk of the bar may be a disadvantage and esthetics may be compromised if spacing is present. Marked lingual inclination of the anterior teeth prevents the use of a cingulum bar. Different laboratory requirements are discussed.

[Removable partial dentures, recent developments].

Improved preventive measures, clinical experience and improved laboratorial procedures have resulted in changes in the design of the removable partial denture. More attention is paid to esthetics, support of free-extension dentures and the biological consequences of the design. Possibilities in prosthodontics concerning these aspects are described.

[Position of removable partial dentures within prosthetic dentistry].

Recent developments in restorative dentistry resulted in a shift towards elderly patients with regard to the application of removable partial dentures (RPD). The half life time of a metal frame RPD is ten years. Negative effects of a RPD on the remaining dentition can be prevented by adequate oral hygiene, which is supervised in a recall program with an individually adjusted interval. Periodontal factors seem to be more important in the design of a RPD than biomechanical factors. Simplicity is a prime guideline in the design, especially in free-end situations.

[Treatment planning in partial prosthodontics].

The aim of the initial treatment is to eliminate active complicating factors from the partial edentulous mouth, such as caries, periodontal disease and occlusal discrepancies. After evaluation of the results of the initial treatment the prosthetic treatment can be started. A specific preparation of the mouth is necessary to accommodate the remaining dentition to the design of the removable partial denture.

[Clinical procedures in removable partial prosthodontics].

Restoring oral function with removable partial dentures includes treatments running along several steps and procedures. These treatments should be carefully planned. The dentist should know the steps to be taken to achieve the desired end result.

[Tooth replacement in the anterior region: specific problems and standard options].

The problems involved in the loss of anterior teeth differ essentially from those in the premolar/molar region. Firstly, missing anterior teeth result in unacceptable changes in appearance and speech, making treatment mandatory. Secondly, the dentist has to consider specific aspects, such as aesthetics, resorption of the alveolar bone, loading of the abutment teeth, form of the clinical crown and incisal guidance. Treatment options comprise orthodontic closure, periodontally supported removable and fixed appliances and appliances supported by implants. The advantages and disadvantages of the different options are indicated.
