Survey on the Current Clinical and Technological Level of Implant Prosthesis Application and Its Complications among Romanian Prosthodontic Specialists.

Objectives: The present study aims to identify the current level of clinical and technological performance of dental prosthetic rehabilitation on implants and the possible existence of correlations between different designs and occurring complications in Romanian practice. Material and method: An online questionnaire with 36 questions, grouped into five sections, has been designed using the Google Forms application. In 2019, it was approved by the Romanian Dental and Maxillofacial Prosthetic Society, and the link to the questionnaire was distributed via email to 70 members. The answers with multiple choice option were summarized in an Excel document, coded and statistically processed in the specific software (SPSS v20.0; IBM Corp). Fisher's exact test, likelihood ratio and linearby- linear association were used, and pairs of two questions were tested considering a standard statistical significance p value=0.05. Results: The results show that screwed rehabilitations (80.5%) on platform switched (70.9%) bone level implant (76.4%) with multiunit (69.1%) abutments for fixed total prosthesis, and custom abutments (43.6%) for removable prosthesis are preferred in Romanian practice. Most common problems of fixed rehabilitation on implants are related to aesthetics (65.5%) and for overdenture to unscrewing (56.4%). Resin-polymerized material in the laboratory, acrylic teeth and milled metallic structure in both arches was the preferred design for fixed restauration in both arches. Multiple statistic significant correlations (p<0.05) were found between the design type and complications. Conclusions: Our findings outline current clinical and technological preferences in Romanian practice on prosthetic implant rehabilitations, illustrating a great need for further research and education consensus.
