Evolution of Chewing Force in Geriatric Edentulous Patients

Objective The aim of this study was to assess the evolution of chewing force in edentulous geriatric patients rehabilitated with complete dentures. Chewing function is compromised in individuals who lose all their teeth, as well as in those with complete dentures. The maintenance and recovery of the chewing function in these patients require replacement of the lost natural teeth. Materials and Methods In this study, the chewing force was evaluated by electromyographic analysis of the temporalis and masseter muscle endings in 120 patients with old and new bimaxillary complete dentures. Results Replacement of complete dentures was shown to improve stability, retention, occlusion, and support of the prosthesis. All jaw movements were evaluated using electromyography to assess the evolution of chewing force with and without occlusal adjustment, identify premature contact points, identify occlusal interference, respect the balanced occlusal scheme, and assess the increase in muscle strength. This study found that muscle strength in patients with prosthesis without occlusal adjustment was 527.1 N but was higher for prostheses with occlusal adjustment at 614.7 N, and this strength of 614.7 N was maintained after 1 month of control. Conclusion The chewing force evolved in patients with complete dentures, and an increase was observed when occlusal adjustment was performed.

FUNCTIONALLY GENERATED PATH TECHNIQUES FOR A HARMONIOUS OCCLUSION – A REVIEW

Harmonious occlusion is a critical prerequisite for successful prosthodontic rehabilitation. Conventional techniques for construction of the prosthesis have not been successful in producing a prosthesis that can be inserted without intraoral occlusal adjustment. The functionally generated pathway (FGP) technique includes registration of the occlusal pathways of the posterior teeth in the functional wax and has been classically described as the "three-dimensional static expression of dynamic tooth movement. The functionally generated path technique employs the patient's masticatory system to develop occlusion. It has various advantages like being simple, accurate, and reliable. The technique will require only minor intraoral occlusal adjustments if done in a proper way. It’s highly versatile and can be utilized to develop occlusal pattern in removable and xed dental prostheses including implant restorations. It can also be employed with equal efcacy in fabrication of relatively simple restorations such as a single crown, or more complex full mouth reconstructions.

The prevalence of trauma from occlusion as the aggravating factors of periodontitis

Trauma from occlusion (TFO) is a local factor that can exacerbate tissue inflammation in periodontitis cases. There have been many clinical studies on TFO, but the prevalence of patients is currently unknown. The purpose of this study was to determine the majority of TFO cases as a factor that aggravates periodontitis based on the medic records at Oral and Dental Hospital, Universitas Syiah Kuala, Banda Aceh, Indonesia in 2017-2019. This study used a comprehensive sampling approach to evaluate 10,532 medical records associated with periodontal disease, including factors such as age, sex, causes, and TFO treatment. Descriptive data analysis showed that from a total of 10,532 medical records, there were 391 medical records related to periodontia. A total of 194 samples matched the inclusion criteria. There were 79 TFO patients (40.7%), 3 TFO cases (1.5%), and 112 cases (57.7%) other periodontal diseases without TFO. The prevalence of TFO as a dominant factor aggravating chronic periodontitis at the Oral and Dental Hospital, Syiah Kuala University, Banda Aceh Indonesia in 2017-2019. Patients with elderly age and female sex predominantly experience periodontitis which is aggravated by TFO.KEYWORDS: Occlusal adjustment blocking method, periodontitis, Trauma from occlusion
