Morphofunctional analysis of the stomatognathic system in conventional complete dentures users from the Integrated Health Center

ABSTRACT This study aimed at characterizing the speech and chewing of users of conventional complete dentures (CCD) before and after speech therapy and prosthetic functional adaptation. The participants consisted of 10 users, divided into two groups: experimental (G1) and control (G2). Both groups underwent the same speech therapy and chewing evaluation before and 15 days after prosthetic functional adaptation; G1 underwent speech therapy in the period before prosthetic functional adaptation, and G2 underwent prosthetic functional adaptation without speech-language intervention. As observed, G1 presented 60% of participants with phonetic and/or articular distortions and inadequate cut of the food and 80% with unilateral chewing; after therapy, no speech and masticatory alterations were observed, but the altered cut was seen in 100% of the group. In G2, 80% of the participants had speech and chewing alterations and 40% had an inadequate cut. After the therapy period, 60% of the subjects remained with speech alterations and 100% with altered cut and chewing alterations. It can be concluded that after prosthetic functional adaptation, the group that underwent speech therapy did not present the alterations initially detected, except for the cut of the food, as opposed to G2 in which the changes persisted, showing that prosthetic rehabilitation alone, did not reestablish functional patterns, speech-language intervention being required.

摘要 本研究旨在分析传统全口义齿（conventional complete dentures, CCD）佩戴者在接受言语治疗及义齿功能适配前后的言语与咀嚼功能特征。本研究共纳入10名受试者，分为实验组（G1）与对照组（G2）两组。两组均接受统一的言语治疗方案，并在义齿功能适配前及适配后15天完成咀嚼功能评估；其中G1的言语治疗于义齿功能适配前开展，而G2仅完成义齿功能适配，未接受言语语言干预。

观测结果显示，G1组初始时有60%的受试者存在语音及/或构音障碍、食物切割方式不当，且80%存在单侧咀嚼；经言语治疗后，该组未再出现言语与咀嚼功能异常，但仍有100%的受试者存在食物切割方式不当的问题。G2组初始时有80%的受试者存在言语与咀嚼功能异常，40%存在食物切割方式不当。经治疗周期结束后，G2组仍有60%的受试者存在言语功能异常，且100%的受试者存在食物切割方式不当及咀嚼功能异常。

综上可得出结论：义齿功能适配后，接受言语治疗的G1组未再出现初始检测到的功能异常，仅食物切割方式除外；而G2组的功能异常仍持续存在，这表明仅靠义齿修复无法重建正常的功能模式，需辅以言语语言干预。
