Clinical effect of Telescopic Crown Retainer and Hollow Prosthetic Appliance on restoring Maxillary Defect after Neoplasm Surgery for the Aged Patient

Objective： To observe the clinical effect of telescopic crown retainer and hollow prosthesis appliance on repairing unilateral maxillary defect after neoplasm surgery for 1- 5 years by follow-up visiting on aged patients. Methods： Twenty-six cases of the aged patients who suffered from unilateral maxillary defect, alveolar bone defect, poor pronunciation caused by mouth and nose connection, and inadequate occlusion clearance caused by severe tooth abrasion after neoplasm surgery were selected. All individuals were implemented with telescopic crown retainer plus hollow prosthetic appliance. After a follow-up period of 1 to 5 years, adaptation, appearance and fitness, maintenance and stability, occlusion and masticatory fimction as well as periodontal condition and so on were observed and detected. Results： It has been shown that the total satisfaction rate with the treatment of telescopic crown retainer plus hollow prosthetic appliance was 61.5%, adequate satisfactory rate was 34.6% and dissatisfactory rate was 3.8%, with general satisfactory rate of 96.1%. Conclusion： The application of telescopic crown retainer plus hollow prosthetic appliance was shown to be satisfactory in repairing unilateral maxillary defect after neoplasm surgery of the aged patients.
