Clinical outcome and technical complications of bimaxillary full-arch implant-supported metal-resin fixed dental prostheses with or without ceramic molars: 5-year results.
Purpose: To evaluate the prevalence of prosthetic-related technical complications (PRTC) for bimaxillary implant-supported fixed complete metal-resin prostheses (ISFP) with (Zrm-ISFP) or without (r-ISFP) occlusal support by incorporation of zirconium molars.
Materials and methods: Two cohorts of patients with bimaxillary ISFP subdivided into test group (TG; Zrm-ISFP) and control group (CG, r-ISFP) providing a 5-year follow-op program were retrospectively analyzed. For both groups the prevalence of PRTC was assessed and compared including evaluation of their occurrence in different time periods (-1 year, > 1-3-years; > 3-5-years post-loading). Additionally, implant/prosthesis survival-rates, peri-implant-marginal bone loss (MBL) and implant-related-technical complications were evaluated and compared.
Results: For the 29 patients with bimaxillary ISFP subdivided into 14 TG [Zrm-ISFP] and 15 CG [r-ISFP]) and followed-up for 5 years no implant and denture loss was seen (survival 100%). However, the prevalence of PRTC such as acrylic-tooth fracture (p < 0.001) and acrylic-tooth repair (p = 0.015) differed significantly between TG (Zrm-ISFP) and CG (r-ISFP). For the CG, an evidently higher time-related ongoing increase (-1 yr: n = 9; > 1-3yrs: n = 23; > 3-5yrs: n = 34) of the prevalence of PRTC was noted compared to TG ( -1 yr: n = 2; > 1-3yrs: n = 3; > 3-5yrs: n = 7). In contrast, PRTC such as denture rebasing/reduction, denture cleaning, screw hole repair and implant-related technical complications and peri-implant MBL did not differ between TG and CG.
Conclusion/clinical relevance: The modified metal-resin ISFPs incorporating zirconium molars/quadrants used for bimaxillary ISFP reduce the prevalence of PRTC and combine beneficial effects such as cost effectiveness and reparability of metal-resin and occlusal stability and reduced wear of complete zirconium prostheses.
期刊介绍：
The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
