Abstract
The objective of the present study was to investigate the effects of various types of fixed prostheses on periodontal tissues and explore the association of gingival biotype and gum recession in relation to prosthesis types. The study participants (N = 95) were divided into three groups based on the type of dental prosthesis: Group-I: cobalt-chrome (Co-Cr) ceramic prosthesis fabricated by the conventional method (n = 35); Group-II: consisted of patients with Co-Cr ceramic prostheses fabricated by a computer-aided design and computer aided manufacturing (CAD/CAM) technique (n = 30); and Group-III: zirconia-based prostheses fabricated by the CAD/CAM technique (n = 30). Following the use of prostheses, periodontal examinations were performed using the Community Periodontal Index (CPI) and Modified Approximal Plaque Index (MAPI). In addition, the gingival biotype was examined using a probe transparency method. The Statistical Package for the Social Sciences (SPSS), Version 20 (IBM Company, Chicago, IL, USA), was used to analyze the results, and the significance level was set at p = 0.05. It showed the MAPI results after the use of prosthetic rehabilitation for 12 months of periodontitis in 87.9% ± 15.4 of patients in Group-I, in 80.6% ± 17.97 in those in Group-II, and in 62.5% ± 21.4 in those in Group-III (p < 0.01). The CPI index results indicated a high prevalence of periodontal disease in all groups. The number of people with healthy periodontium constituted 17.1% of patients in Group-I, 24.2% in Group-II, and 37.1% in Group-III. Our study concluded that prosthetic treatment with periodontal diseases showed better outcomes while using dental prostheses fabricated by the CAD/CAM technique compared to the conventionally fabricated dental prostheses. The thin gingival biotype is more often associated with gingival recession than the thick biotype.
Highlights
The functional disorders of the stomatognathic system due to periodontal diseases are five times more frequent than those resulting from dental caries [1]
A total of 24 subjects were healthy without any complaints or periodontal pathology, while 39 patients were diagnosed with gingivitis and 32 patients with periodontitis
It was reported that there was no significant differences in cell viability and migration ability of human gingival fibroblasts (HGF) and HOK on computer-aided design and computer aided manufacturing (CAD/CAM) all-ceramic materials [30]. These results suggested a high biocompatibility of all the CAD/CAM prosthesis and had no significance influence on adenylate kinase (ADK) secretion by HGF and HOK maintaining their energy hemostasis
Summary
The functional disorders of the stomatognathic system due to periodontal diseases are five times more frequent than those resulting from dental caries [1]. The goal of the fixed prostheses is to control oral disease while restoring aesthetics and function with durable, biocompatible restorations. Knowledge of the responses of periodontal tissues to fixed prostheses and periodontal aesthetics are important in the development of treatment plans with predictable prognoses and patients’ acceptance [7]. Biofunctionality and the harmony between the prosthesis and the periodontium is important for the aesthetics and longevity of the prosthesis [7]. In this regard, several factors, such as the prosthesis design, pontic design, occlusion, and biomaterial may contribute and should be considered while planning the fixed prosthodontic treatment [8]
