Denture, Complete, Immediate↗

Esthetic and emotional factors in immediate denture construction.

Some patients delay the extraction of infected teeth because of the fear and dread of becoming edentulous. In immediate denture service, the humiliating edentulous period is eliminated. An immediate denture is defined as a "denture constructed for insertion immediately following the removal of the natural teeth" and is desirable and indicated for a majority of patients who lose their remaining teeth. This article discusses techniques and materials used in the preparation of immediate dentures.

Denture, Complete, Immediate↗

Immediate complete prostheses with fibrous carbon artificial roots.

An original immediate denture technique, combined with the insertion of fibrous carbon artificial (implant) roots is described. The method presents two main characteristics: 1) construction in the laboratory of a "matrix-base", which provides a "skeleton" for the final prosthesis; 2) a change in the sequence of the operative procedure. The final impressions are made after treatment, wax try-ins and surgery, immediately prior to processing the prosthesis. Among the advantages of this technique are the following: the "matrix-base" avoids making an intricate individual impression-tray. The remodelling of the plaster model is simplified in the laboratory. The artificial undersurface is shaped exactly to the tissues, following tooth extraction, when the secondary impressions are taken. The patient may contribute to ensure the optimal "esthetic reproduction" before denture processing. The technique of impacting fibrous carbon implants is simple and enables the optimal maintenance of the alveolar bone volume. The denture made with this technique provides an immediate denture, physiologically integrated into the tissues which it covers or which surround it. The middle and long term clinical results are always highly satisfactory.

[Immediate loading of dental implants in partialful edentulous and edentulous jaws].

OBJECTIVE: To investigate the clinical feasibility and technical characteristics of immediate loading and to access the short-term clinical results of treatment. METHODS: This study included 3 completely edentulous patients and 24 patients who were partially edentulous from March 1999 to December 2003. 21 implants were immediately loaded and provided support for mandibular overdenture for 3 fully edentulous patients. 30 implants were placed in 21 partially edentulous patients and implants were immediate loaded in edentulous mandibular providing support for fixed provisional prosthesis within 6 months. Then, metal-ceramic crowns were completed. All patients were followed up by 1, 3, 6, 12 months and the patients were checked every 12 months. RESULTS: A total of 42 implants were loaded immediately. From March 1999 to December 2003, no implants were lost during follow-up (range 3 to 49 months, mean of 28 months). No infections, nerve or sinus damage or other sequelae occurred. No implants exhibited peri-implant radiolucencies. Moreover, immediate loading seems to increase the ossification of the alveolar bone around endosseous implants. Patients were satisfied with the treatment. CONCLUSIONS: The data and the experience described in this study indicate that immediate loading with restorations using appropriate surgical and restorative techniques can predicate the completely edentulous and partially edentulous mandible in some cases. Further study is needed to determine the long-term result of immediately loaded implants.

Immediate functional load of mandibular implant overdentures: a surgical and prosthodontic rationale of 2 implant modalities.

Classic guidelines in osseointegration for root-form dental implants include a long healing period, during which functional load should be avoided. However, the long healing period might impose an intolerable situation on some patients, especially in the completely edentulous situation. Subperiosteal dental implant guidelines demonstrate that the implant upon insertion can be put into immediate function and be restored with the final prosthesis soon after surgery. Studies on immediately functional loaded implant-supported prostheses in patients who are completely edentulous have been reported, exhibiting high success rates comparable with conventionally loaded implants. This article describes the surgical and prosthodontic procedure for the immediately functional loaded mandibular implant overdentures in 2 different dentalimplant modalities, as well as its clinical rationale.

Dental Implantation, Endosseous↗

Early and immediate restoration and loading of implants in completely edentulous patients.

Primary stability and postponement of loading of dental implants for approximately 3 to 6 months have been considered for years the "conditio sine qua non" to allow osseointegration of dental implants. However, in recent years, an increasing number of publications on immediate and early loading of dental implants in completely edentulous patients have appeared in the literature, and high survival rates were generally reported. Nevertheless, much controversy still exists over the reliability of the reported data, frequently because the publications are of insufficient methodologic quality (insufficient follow-up, inadequate sample size, absence of randomization, lack of well-defined exclusion and inclusion criteria, lack of well-defined success criteria, etc). The objective of this study was to review the literature to evaluate the reliability of early and immediate loading of implants placed in the edentulous mandible and maxilla and rehabilitated either with implant-supported overdentures or with implant-supported fixed prostheses.
