Alveolar socket preservation and shaping using temporary prosthetic construction – case presentation
Introduction - Postextraction bone resorption usually results in reduced, deficient and sometime even defective alveolar ridge compromising the fabrication, hygiene and esthetic of the gingival part of pontic design. The deficiency of the partial ridge due to bone resoption is normal and expected, but it,s intensity and shape can be improved with proper planning and fabrication of immediate temporary construction prior the tooth extraction.
Objective - The aim of the study is to present and investigate the effect of alveolar socket preservation and partially toothless residual ridge shape using immediate fixed or removable temporary prosthetic construction in cases with single tooth extraction indication.
Material and method – Immediate temporary removable single tooth denture (4 cases) or temporary bridge (3 cases) were fabricated in 7 patients with indication of tooth extraction. The specific element in both prosthetic constructions is a small false root (4-5 mm) inserted in the postextraction alveolar socket. This pseudo-root was periodically corrected and decreased in height every 2 weeks.
Results – The prosthetic construction applied immediately after extraction protects the alveolar socket allowing undisturbed healing and ossification. The short pseudo-root inserted in the cervical part of the alveolus gives support and prevents collapse of the soft tissue. Recommended period for using temporary construction is 8-12 weeks.
Conclussion – The benefit of this simple procedure is to achieve faster healing of the postextraction socket and desirable shape of the toothless area. The disadvantages are necessity for proper planning prior the tooth extraction, relatively long period for shaping of the alveolar ridge and frequent adjustments of the immediate temporary construction.
