Area of Science:

  • Dentistry
  • Biomaterials Science
  • Prosthodontics

Background:

  • Dental prosthetic rehabilitation is crucial for restoring function and aesthetics.
  • Understanding complications of implant-supported prostheses is essential for long-term success.
  • Previous studies have indicated varying complication rates, necessitating further investigation.

Purpose of the Study:

  • To evaluate the frequency and types of technical complications associated with implant-supported prostheses.
  • To identify factors contributing to these complications.
  • To provide evidence-based recommendations for minimizing complications in dental prosthetic rehabilitation.

Main Methods:

  • A retrospective, one-time snapshot study design was employed.
  • Data were collected from 153 patients with a total of 509 implants.
  • Prosthetic conditions were assessed through comprehensive clinical and radiographic examinations.

Main Results:

  • The most frequent technical complications were loss of resin covering the screw (23.8%), loss of overdenture retention (18.6%), and resin fractures (12.4%).
  • Screw-related complications like fracture (0.2%), loss (0.4%), and loosening (3.3%) were infrequent.
  • A significant frequency of prosthesis-abutment misfit (25.4%) was observed, particularly with cemented prostheses (P < 0.001).

Conclusions:

  • Technical complications in implant-supported prostheses are common, with resin-related issues and misfit being prevalent.
  • Establishing robust protocols from diagnosis through follow-up, including meticulous technical procedures and radiographic evaluation, is vital.
  • Further research and standardized protocols are needed to enhance the prognosis and minimize complications in dental prosthetic rehabilitation.
