Clinical Evaluation of Complications in Implant-Supported Dentures: A 4-Year Retrospective Study

Abstract

BackgroundImplants that can be used in the prosthetic rehabilitation of full and partial edentulous patients are now frequently used due to advances in dentistry. Despite advanced methods of applications, failures and complications can still be seen. The aim of our study was to evaluate clinical prosthetic values and complications that occurred during 4-year follow-up in implant-supported restorations.Material/MethodsThis retrospective study included 40 patients who received oral rehabilitation with an implant-supported prosthesis. A total of 162 implants were placed: 99 in the maxilla and 63 in the mandible. The prosthetic and surgical data were recorded. Data including prosthetic complications and implant loss were recorded and statistically analyzed using Cox proportional hazard regression analysis.ResultsIn total, 159 implants (98.14%) survived, 3 implants (1.86%) failed, and 100% of the protheses were successful. There were 62 dental implants used as abutments for removable dentures and 97 for fixed dentures. The most frequent prosthetic complications after placement of an implant-supported prosthesis were loss of retention, mucositis, abutment screw loosening, and fracture. Patient satisfaction after prosthesis use was also evaluated, showing that satisfaction was systematically increased.ConclusionsTo minimize the frequency of complications, protocols must be established from diagnosis to the completion of treatment and follow-up of implant-supported prostheses, especially in terms of adequate technical steps and careful radiographic evaluation of the components.

A 5-Year Satisfaction Outcome Study of Patients Receiving Six-Implant-Supported Fixed Prosthesis

“…In our case protocol, peri-operative care was discussed thoroughly with the patient, including the delayed loading protocol and further recall visits needed. The implant CSR in our study was found to be 99%, which is slightly better than the study by Eliasson [ 11 ], where they found it to be 92–94.4% of implant survival rate in the early loading group compared to 98% at the delayed loading group; the result of a five-year recall study [ 10 , 11 ].…”

“…One retrospective study included 40 patients who had a similar treatment protocol to the one used in our study of the 6IFP plan and were followed for 4 years. The study reported an implant survival rate of 98%, and 100% prosthetic success, except for minor issues that were managed conservatively such as loosening of the abutment screws, mucositis, or prosthesis minor fractures, which were encountered in a few cases in our series [ 10 ]. In our case protocol, peri-operative care was discussed thoroughly with the patient, including the delayed loading protocol and further recall visits needed.…”

A Review of Current Concepts in Full Arch Rehabilitation with Dental Implants

“…The most frequent prosthetic complications after the placement of an implantsupported prosthesis are: mucositis, loosening or fracture of the abutment screw or prosthetic components, and fracture of the acrylic or porcelain structure. Although most complications resolve favorably in follow-up appointments, it is essential to establish an adequate surgical and prosthetic management protocol to achieve predictable and successful long-term results [49,50].…”

Remote Management of Prosthodontic Emergencies in the Geriatric Population During the Pandemic Outbreak of COVID-19

“…Prosthodontic complications commonly occur with a removable implant-supported prosthesis, ranging from loss of retention of attachment systems to loosening of screws ( 31 ). Biological emergencies usually include gingival hyperplasia beneath a bar, which can lead to failure of the denture to the seat.…”
