“…This condition is considered to be a risk factor for occlusal instability, as extensive and uncontrolled migration of the teeth might occur leading to collapse of the bite (mandibular overclosure) and further breakdown of the dentition (Ramfjord & Ash, 1983;Mohl et al, 1988; Thomson, 1990). This occlusal collapse is also described by Stern & Brayer (1975) as they stated: 'Pathological changes of the occlusion may occur when posterior tooth support is reduced or lost'. Pointing to the aetiology they noted: 'One of the commonest causes of occlusal collapse is the unreplaced loss of the lower first molar.…”

In this clinical 6-year follow-up study subjects with shortened dental arches (SDA, n = 55), characterized by the absence of molar support, are compared with subjects with complete dental arches (CDA, n = 52) with respect to occlusal stability. In addition, a small group of subjects with SDA and removable partial dentures in the lower jaw (SDA+RPD, n = 19) is included in this study. The aim of this study was to describe effects regarding occlusal stability in subjects with SDA during a 6-year period. The applied parameters for occlusal stability are: number of occlusal contacts in the anterior region, overbite, interdental spacing and alveolar bone support. The results of this study show that: (i) SDA do provide durable occlusal stability; (ii) free-end RPD do not contribute to occlusal stability in SDA; and (iii) SDA with periodontally involved teeth show continuing periodontal breakdown.

“…It is thought that posterior support prevents or reduces manifestations of the so-called posterior bite collapse. This collapse is accompanied by migrations in the premolar regions, interdental spacing, decrease in vertical dimension, changes in temporomandibular condyle position, overeruption of unopposed teeth, and increased vertical overlap and flaring of anterior teeth [7]. Previous studies showed that in moderate shortened dental arches these phenomenons are just limited or even absent.…”

Objective. To quantify effects on occlusion and temporomandibular function of mandibular distal extension removable partial dentures in shortened dental arches. Methods. Subjects wearing mandibular extension removable partial dentures (n = 25) were compared with subjects with shortened dental arches without extension (n = 74) and with subjects who had worn a mandibular extension removable partial denture in the past (n = 19). Subjects with complete dentitions (n = 72) were controls. Data were collected at baseline and at 3-, 6-, and 9-year observations. Results. Occlusal activity in terms of reported awareness of bruxism and occlusal tooth wear of lower anterior teeth did not differ significantly between the groups. In contrast, occlusal tooth wear of premolars in shortened dental arches with or without extension dentures was significantly higher than in the controls. Differences amongst groups with respect to signs and symptoms related to temporomandibular disorders were not found. Occlusal support of the dentures did not influence anterior spatial relationship. Occlusal contacts of the denture teeth decreased from 70% for second premolars via 50% for first molars, to 30% for second molars. Conclusions. Mandibular distal extension removable partial dentures in moderate shortened dental arches had no effects on occlusion and temporomandibular function.

Although a traditional clinical concept of prosthetic intervention on molars without antagonist is still believed among a great majority of Japanese dentists, a "wait-and-see" policy seems to be accepted in this clinical situation by some prosthetic specialists. AbstractPurpose: The aim of this questionnaire study was to survey Japanese dentists' perceptions of risks for overeruption of unopposed molars and dentists' attitudes to prosthetic intervention. Methods:A clinical situation with a 42-year-old male patient who just had lost the left mandibular molars was presented. A series of questions was provided regarding what would most probably occur with the unopposed maxillary molars within a 10-year period, what treatment to propose, and indications for the proposed treatment. The questionnaire was sent to the council members of the Japanese prosthodontic society, doctors of Matsumoto Dental University, members of the Nagano and Niigata prefecture dental societies via letter, facsimile or E-mail.Results: 887 of 1320 (67%) dentists returned completed questionnaires. The great majority believed that overeruption of the unopposed molars would occur within a 10-year period (94%). 87% of respondents wanted to perform prosthetic treatment. In contrast, a "wait-and-see" alternative was chosen by only 12%. The most commonly suggested indications for the treatments were the risk for overeruption (96%) followed by impaired masticatory function (77%) and development of TMD (73%). Conclusion:To date, the majority of Japanese dentists seem to believe that overeruption of molars would occur after extraction of antagonists, and that prosthetic interventions are necessary to prevent possible clinical problems.

Collapse of the occlusion—aetiology, symptomatology and treatment

Abstract: Aetiological factors which lead to occlusal collapse have been surveyed and the clinical symptomatology of this syndrome emphasized. The sequence of periodontal treatment as well as suggestions for re-establishing and recording new jaw relations are discussed in detail.
