[Augmentation of the maxillary sinus floor and alveolar ridge for placement of endosseous implants in the edentulous maxilla].

Placement of endosseous implants in the atrophic maxilla is often restricted because of lack of supporting bone limiting placement of implants of adequate length in a prosthodontically optimal position. There are several surgical procedures to create sufficient volume of bone for the placement of implants. In this paper, a technique is described for augmentation of the maxillary sinus floor and simultaneous widening of the alveolar crest with autogenous bone.

Augmentation of localized defects of the anterior maxillary ridge with autogenous bone before insertion of implants.

PURPOSE: This study evaluated the applicability of intraorally harvested autogenous bone grafts for the augmentation of the narrow maxillary alveolar ridge to enable insertion of implants for single tooth replacement. MATERIALS AND METHODS: Local defects of the anterior maxilla were reconstructed in 27 patients with autogenous bone grafts from the mandibular symphysis (n = 12), maxillary tuberosity (n = 8), or mandibular retromolar area (n = 7). Three months after grafting, either Branemark (n = 23) or ITI Bonefit implants (n = 8) were inserted. RESULTS: At the time of implantation, all grafted sites showed sufficient bone volume for insertion of the implants. Twenty-four to 68 months after insertion, all implants were functioning well. CONCLUSION: Augmentation of local alveolar defects in the maxilla with intraorally harvested autogenous bone grafts appears to be a reliable method to enable implant placement.

Overdentures supported by two IMZ implants in the lower jaw. A retrospective study of peri-implant tissues.

Between 1987 and 1990, 57 edentulous patients were treated with overdentures supported by 2 endosseous IMZ implants connected by a bar in the lower jaw. The condition of the peri-implant tissue was evaluated for a loading period ranging from 12 to 57 months (mean 30 months and median 24 months). The evaluation parameters included Plaque Index, Bleeding Index, Gingiva Index, pocket depth, dysesthesia of chin or lip, peri-implant bone loss and loss of implants. During the healing phase prior to the construction of an overdenture, 3 implants were lost. After a healing period of 6 months, these implants were successfully replaced. During the follow-up period, a Plaque Index < or = 1 was observed in 45 patients and an abundance of plaque and calculus was observed in 1 patient. Heavy or profuse bleeding and severe gingival inflammation was observed in 3 patients. The mean pocket depth was 3.6 +/- 1.7 mm. None of the patients experienced lip or chin dysesthesia. Marginal bone loss was observed around 30 (26%) implants. From this study it is concluded that, once proper osseointegration is obtained, 2 IMZ implants connected with a bar in the lower jaw supply a proper base for the support of an overdenture; the condition of the peri-implant tissues is steady and independent of the follow-up time.

Use of the final denture base for the intermaxillary registration in an implant-supported overdenture: technical note.

A method of implant-retained overdenture treatment based on the early use of the final denture base during registration of the maxillomandibular jaw relation is described. Using this stable denture base, an accurate recording of jaw relation and an adequate try-in procedure are facilitated without displacement of the base, especially in the situation of an unfavorable flat edentulous mandibular residual ridge.

[The making of an overdenture supported by two endosseous implants in the lower jaw].

Due to extreme alveolar resorption many edentulous patients wearing complete dentures suffer from loss of function of the orofacial system. Improvement of oral functions can be obtained by increasing the denture-support, using implants. The construction of a combined implant/mucosal supported lower overdenture will be helpful. A method to construct an overdenture on oral implants is described.

[The impression procedure for overdentures supported by two endosseous implants in the lower jaw. A comparison among three permucosal implant systems].

The procedure to make an impression for the construction of an overdenture on endosseous implants in the lower jaw is not the same for all implant systems. Impression-procedures for a two-phase screw type implant (Brånemark), a two-phase cylinder type implant (IMZ) and a one-phase implant (ITI Bonefit) are described.

Influence of patient age on the success rate of dental implants supporting an overdenture in an edentulous mandible: a 3-year prospective study.

The aim of this study was to determine the influence of age on peri-implant tissues in patients treated with implant-supported overdentures in the mandible. A prospective study was carried out with 2 groups of healthy edentulous patients. The mean age of the younger group (n = 32) was 46 years (range 35 to 50 years); the mean age of the older group (n = 26) was 68 years (range 60 to 80 years). Two dental implants were placed in the interforaminal region of the mandible, and after a 3-month healing period, overdentures were fabricated. Clinical and radiographic parameters were evaluated immediately after completion of the prosthetic treatment, after 1 year, and after 3 years. The evaluated clinical parameters were implant loss, Plaque Index, Gingival Index, Bleeding Index, and probing depth. Radiographic evaluation was performed using a standardized long-cone technique with a direction device. Statistical analysis was carried out with SPSS software. One implant in the older group was lost during the healing period. After 3 years, the mean scores for Plaque Index, Gingival Index, and Bleeding Index were between 0 and 1 for both groups (out of possible scores of 0 to 3), and the mean probing depth was 3 mm in both groups. The mean bone loss after 3 years was 1.2 mm in the younger group and 0.8 mm in the older group, but this difference was not significant. It was concluded from this study population that the clinical performance of implant-supported overdentures in the mandible is equally successful in younger and older patients.

Treatment concept for mandibular overdentures supported by endosseous implants: a literature review.

Edentulous patients with a severely resorbed mandible often experience problems with their dentures. Treatment concepts involving two to four implants for the support of an overdenture have been proposed. The aim of this study was to develop a treatment concept for mandibular overdentures supported by endosseous implants based on a review of the literature. It is proposed that two implants supporting a mandibular overdenture (bar construction) are sufficient for most applications. Four implants were indicated in situations involving a dentulous maxilla, a narrow mandibular arch, extreme resorption of the mandible (bone height greater than 12 mm), and mandibular soreness and pain.
