Single tooth morse taper implant placement and restoration immediately after extraction

Abstract

Objective: to analyze aesthetic and functional outcomes of the rehabilitation of single tooth morse taper implant restoration with single crown prosthesis immediately after tooth extraction. Methods: Retrospective longitudinal clinical study of 57 patients submitted to an oral rehabilitation protocol with morse taper (Ankylos® Classic) dental implants, without performing incision, grafts nor suture, followed by the placement of a provisional prosthesis immediately after tooth removal in the anterior maxillary region. The pre-and post-operative clinical data (alveolar bone contour at vestibular aspect, soft tissue contour at cervical aspect and papillae level) and postoperative radiographic findings (bone height / implant ratio) were submitted to descriptive statistics (mean and standard deviation) and Fisher’s Exact Test. Results: the implant success rate was 98.25%. The alveolar bone vestibular aspect was maintained in 69.6% of the cases. There was no soft tissue retraction on the cervical aspect and the papillae height was preserved in 89.3% of the cases.The bone level remained above the implant neck in 92.8% of the cases. There was no significant association between implant diameter and soft tissue retraction (p = 0.910) or retraction of the interproximal papilla (p = 0.148) or resorption of the alveolar bone crest (p = 0.610). Conclusion: This protocol is characterized by the application of minimally traumatic techniques, reducing rehabilitation time and offering positive aesthetic and functional results.
