Rationale for Choices of Occlusal Schemes for Complete Dentures Supported by Implants

Abstract

This review of occlusal considerations for implant-supported complete dentures reflects the majority opinion of authors according to clinical observations and research-documented evidence. Occlusal concepts are presented for the implant-supported complete dentures regarding analysis of loads applied to dental implants, location and number of implants, occlusal materials, and occlusal scheme.

Prosthetic complications and maintenance of implant retained maxillary and mandibular overdentures constructed with fully balanced and lingualized occlusal schemes : Randomized control clinical trial

“…This may reflect the increased occlusal pressure and load transmission to the locator attachments when fully balanced occlusion was used compared to lingualized occlusion. This could be attributed to the architecture of fully balanced occlusion that has more occlusal contact points on functional and non-functional cusps on the loading (chewing) side during lateral mandibular excursions as well as during protrusive movements of mastication 43 . Moreover, fully occlusal concept using anatomic teeth, so occlusal disharmonies (locking of occlusion) may occur by settling of denture base (as a result of mucosal resiliency and vertical resiliency of the nylon inserts) which is difficult to be corrected 43 .…”

Four narrow dental implants and conventionally cast bar‐supported removable hybrid acrylic complete denture as a therapeutic modality for terminal dentition

“…The habitual protrusion did pose difficulties during jaw relations; it was not easy to manipulate the patient's jaw due to some degree of TMJ dysfunction, chronic pain, and tenderness on palpation; the occlusion was adjusted several times by selective grinding during the delivery and follow‐up appointments. An appropriate occlusal scheme for an RCD is debatable; we provided a balanced occlusion based on the published guidelines 34 . Toward the end, a significant recovery of the patient from TMD was recorded, demonstrating the importance of accurate maxillomandibular relations for an optimum TMJ health.…”

Maxillary restoration with complete maxillary prosthesis supported by implants with immediate loading: clinical retrospective study of 48 cases

“…Although no study proves the superiority of this technique, a majority of authors agree that this scheme allows to minimize the most the traction forces applied to implants and to spread the compressive forces over the whole of the arch [28]. To steer the most the masticatory forces in the axis of the implants, lateral stress and intercuspation interference must be decreased by limiting the heights and intercuspation slopes as well as the depth of the fossae [29].…”
