“…P. Calderon et al, 2014 reported that the most frequent complications were loss of resin covering the screw (23.8 %), loss of prostheses retention (18.6 %) and fractures of the resin (12.4 %) [5]. A high frequency of misfit between the prosthesis and abutment (25.4 %) was found, which was significantly associated (p < 0.05) with other variables [5].…”

Objective-to study features of biomechanical complications (structural fractures, loss of retention, screw loosening/fracture) of implant restorations in different terms of functional loading and work out preventive measures. Materials and methods. The results of prosthetic treatment with implant supported fixed dental prostheses were analyzed among 65 patients, who were treated between 2011 and 2016. There were 28 (47.1 %) men, 37 women (56.9 %), the average age of patients was 35.6 ± 12.7 years. All patients had small defects of dentition in posterior region without severe periodontal or general pathology. Prosthetic treatment was performed on two-staged osteointegrated "root form" implants with a screw design. According to the objective of the study all patients were divided into three groups depending on the period within implant placement and tooth extraction (6-8 month or more than 2 years), the terms of functional loading and usage of protective occlusal splits. The incidence of biomechanical complications and functional activity of masticatory muscles were detected. Results. The incidence of mechanical complications during 5-year period was 3.85 times higher in patients with long-term existing defects of dentition after tooth extraction and conventional prosthetic treatment with deferred occlusal loading (3 cases (15 %) of loss of retention, 5 cases (25 %) of veneering material fracture, 1 case (5 %) of abutment screw loosening and 1 case (5 %) of abutment screw fracture) in comparison to patients with early functional loading and shorter period after tooth extraction (1 case (4.3 %) of loss of retention and 2 cases (8.7 %) of veneering material fracture). Protective occlusal splints' application and early functional loading in prosthetic treatment of patients with long-term existing defects of dentition after tooth extraction allowed to decrease the incidence of mechanical complications in 1.57 times in comparison to conventional treatment with deferred loading. Conclusions. The incidence of biomechanical complications of implant restorations is higher in patients with long-term existing defects of dentition after tooth extraction and deferred occlusal loading in comparison to cases of well-timed prosthetics and early functional loading. Protective occlusal splints are proved as effective preventive measures to decrease the incidence of mechanical complications of implant supported fixed dental prostheses and to induce faster normalization of masticatory activity.

DT played a role and took decisions regarding the DIP. Frequent problems found by DT were poor implant location, discrepancies in impression/bite-registration, facing damage/chipping and damage/fracture of the denture base/prosthetic teeth. The frequency of these complications can be minimized by an increase in the prosthetic knowledge of the dentists and establishing clear protocols for communication between the dentist and the DT.

“…The stripped abutment screws represented another complication. Potential causes of such complications include unfavorable implant distribution, inadequate fit of the prosthesis, metal fatigue, manufacturing defects, occlusal overload, and parafunctions …”

Fracture and loosening of implant-supported prostheses (ISPs) are complications encountered in routine dental practice. In the present report, management of a fractured maxillary full-arch cement-retained (CR) fixed dental prosthesis supported by six implants is presented. Due to stripped screws, complications were encountered that prevented the retrieval of two of the six abutment screws, which was managed by using a hybrid retention approach, whereby a single full-arch CR and screw-retained (SR) ISP was used. The techniques used to successfully retrieve four of the abutment screws are described. The final retention design involved a combination of three CR and three SR restorations, which offers the advantages of both retention designs.
