PENGARUH ANATOMI STRUKTUR PENDUKUNG GIGI TIRUAN PENUH RAHANG BAWAH TERHADAP RETENSI DAN STABILISASI
Complete edentulous is a condition which a person loses all of his or her natural teeth. The treatment is done by making a complete denture (CD). The parameter of successful treatment is dependent on its use. Patient’s ability to adapt to new CDs is often becomes the problem. If it’s not solved properly, it will impact the oral health and quality of life of the patients, so post-treatment evaluation and control are important. One problem that is widely complained is the retention and stability of lower CD. According to previous studies, the patient's adaptation to CD is related to the condition of dentures, which is a combination of CD’s quality and characteristics of alveolar ridges, so the difference between dentist's evaluation of CD’s quality and patient's subjective assessment could happen due to improper clinical assessment of denture-bearing area, which consists of anatomy of supporting and limiting structures. However, other researches suggest alveolar ridges don’t affect patient acceptance of CDs, so studies in this area are still considered equivocal. The purpose of this study is to determine the influence of anatomy of lower complete denture supporting structures on retention and stability. This study is a descriptive analytic research with clinical examination of lower denture and oral cavity. Total of samples are 30 CD patients those fulfill the inclusion and exclusion criteria. The result of this study based on the Fisher Exact Test showed a significant influence between the anatomy of lower complete denture supporting structures on retention and stability.
