Abstract
Choosing an adequate occlusion is challenging during the construction of artificial dentures, and critical for patient satisfaction. However, there is no conclusive evidence to support which occlusal design is more appropriate. The aim of this systematic review was to evaluate canine-guided occlusion in comparison to other occlusal schemes in removable complete denture wearers. The review was conducted according to the Preferred Reported Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. An extensive search was carried out on (PubMed (National Library of Medicine)), Scopus (Elsevier), Cochrane collaboration (Wiley), Science Direct (Elsevier) and Europe PMC (European Bioinformatics Institute). English and non-English studies were identified using keywords on canine-guided occlusion, denture occlusion, dental occlusion and artificial occlusal schemes. Out of 1759 articles searched, 18 were selected based on the inclusion criteria. The included studies were interpreted for the descriptive analysis for the calculation of occlusal schemes, occlusion assessment parameters, the outcome of the occlusal schemes and types of removable prosthesis used. The systematic analysis of occlusal schemes revealed that canine-guided occlusion is viable compared with other occlusal designs in terms of patient satisfaction, mastication, retention, esthetics, phonetics, oral-health-related quality of life and muscle activity. The type of occlusal scheme influences the complete denture patient’s’ masticatory efficiency, satisfaction, retention, phonetics and esthetics. Nevertheless, physical, physiological, mechanical and psychological factors play a vital role in the success of removable complete dentures. The canine-guided occlusal scheme is preferred because of its simplicity, less time consumption, good masticatory performance, ease of fabrication and modification into bilateral balanced occlusion if required. Further studies are required to reduce the controversies related to jaw relations, gnathology and occlusal schemes in complete dentures.
Highlights
Removable complete denture (CD) occlusal schemes have a varied perception in terms of satisfaction and oral-health-related quality of life in patients [1]
canine-guided occlusion (CGO) is a viable alternative to bilateral balanced occlusion (BBO) in complete dentures
To date, there is no conclusive evidence to support which occlusal scheme is appropriate for the construction of a successful and support which occlusal scheme is appropriate for the construction of a successful and functional complete denture [39]
Summary
Removable complete denture (CD) occlusal schemes have a varied perception in terms of satisfaction and oral-health-related quality of life in patients [1]. The three pillars for the success of removable dentures are retention, stability and support, which directly affect the function, phonetics and aesthetic of patients. The factors are associated with restorations in both arches but complicated in the mandibular arch. Problems are associated with artificial dentures of both conventional and implant-supported categories with continuous denture use [2]. The use of tissue-friendly techniques and materials can improve the patient satisfaction level and biocompatibility [3]. Occlusion is an integral component of complete denture biomechanics. Satisfactory occlusal scheme prescription is a supporting factor to a better removable complete denture outcome in patients. It is evident that adjusting the occlusion clinically and in laboratory increases patients’ acceptance with time [4]
