Bilateral Mandibular Posterior Edentulous Rehabilitation for Unstable Occlusion Patient with Bilateral Attachment Retained Mandibular Removable Partial Denture

Abstract

A 62-year-old female patient came to the Dental Hospital of Universitas Airlangga to maintain her remaining teeth and make dentures for the missing teeth, and expressed that she expected a high aesthetic result. The patient had lost bilateral posterior mandibular teeth, resulting in unstable occlusion. To stabilize the occlusion, this patient was treated by temporary denture. After 3 months of follow up and confirmed adaptation with the new occlusion, prosthodontic treatment was done consisting of bilateral attachment retained mandibular removable partial denture, aimed at the patient’s expectation of acquiring good aesthetic results and functional rehabilitation.

Association between the number of bilateral free-end posterior tooth loss and mastication performance in RSGM USU patients

“…If in a bilateral free end state, a person tends to use anterior teeth to replace their function so that they tend to advance the chin and cause instability. 18,19,20 The number of remaining teeth in occlusion also affects masticatory function because the smaller the number of remaining teeth in occlusion, the lower the masticatory performance. 26 The results of the study in tables 1 and 2 show that the prevalence of bilateral free end posterior tooth loss in one jaw arch is more dominant in losing >4 teeth (55.6%) and in both jaw arches is more prevalent in losing >10 teeth (87.5%).…”

“…14,15,10,16 If in a bilateral free end state, it will cause difficulty and limitations in mastication so that a person tends to advance the chin and result in occlusion instability which has an impact on masticatory function and jaw movement processes. 17,18,19,20 Good occlusion should allow the mandible to translate without occlusal resistance during functional movements, especially the posterior part, so that the load distribution is more even. 21 Occlusion and mandibular position will be expected and stable if each masticatory component can carry out its activities, usually with harmonious and balanced interactions.…”

NFkB and MMP-13 expression in condylar cartilage of temporomandibular joint with occlusal disharmony in vivo

“…The occlusal interference causes abnormal masticatory function and induces the deterioration of TMJ tissue homeostasis. 31 In another study, MMP13 was linked to the presence of pathological conditions of chondrocyte cells and occurred in the early phase of osteoarthritis. 27 MMP13 is a major enzyme that degrades the extracellular matrix by breaking peptide bonds in target proteins, so it will break down collagen and proteoglycans.…”
