Publication Radiographic Evaluation of Crestal Bone Loss in Pre-loading and Post-loading States of Endosteal Implants in Maxilla and Mandible- A prospective study(Kathmandu University, 2023) Lamichhane, S; Humagain, M; Bhusal, S; Rijal, AH; Rupakhety, PABSTRACT Background Peri-implant tissue integrity depends upon healthy peri-implant mucosa and bone. The crestal bone is one of the governing factors for successful implant therapy both functionally and esthetically. There are limited radiographic studies in Nepalese population for determination of crestal bone loss around peri-implant area comparing the bone loss at pre- and post-loading state. Objective To evaluate the bone loss in mesial and distal, maxilla and mandible before and after the implant supported prosthesis delivery. Method A 6-months prospective study was planned and conducted in 26 endosteal implants (13 maxillary and 13 mandibular) which were placed in 20 patients fulfilling the inclusion criteria. The crestal bone loss was measured and compared using digital radiography images using the designated software. The differences among the crestal bone loss in mesial and distal, maxilla and mandible in pre- (3 months of implant placement) and post-loading states (3 months of prosthesis delivery) were evaluated using the appropriate statistical tests. Result The crestal bone loss was more pronounced in the pre-loading stage (1.12 mm) compared to post-loading (0.48 mm). Initially, the bone remodelling was higher in the distal aspect whereas there was no significant difference between mesial and distal aspect in post-loading phase. Comparing maxilla with mandible, there were no significant differences in bone loss in both phases. Conclusion Within the limitations of this study, the crestal bone loss was found upto the physiological limit of bone remodelling provided the implants placed in strict, aseptic condition with proper case selection and planning.

The prosthetic options for such case include either prefabricated prosthesis or custom-made prothesis. Various materials and techniques are used for the fabrication of the prosthesis. Semi-customized prosthesis uses stock iris while the scleral shell is customized. This prosthesis has the advantages of both stock and custom-made prosthesis providing functionally and esthetically satisfactory result. This case report demonstrates the case of a 32 years old male who reported to the Department of Prosthodontics and Crown-Bridge, College of Dental Surgery, BP Koirala Institute of Health Sciences, Dharan, Nepal for eye prosthesis to mask his pthisical eye. For this case, a semi- customized scleral shell prosthesis was planned and fabricated.

Objective To assess the knowledge and attitude of general dental practitioners towards specialist periodontal referral. Method This cross-sectional study was carried out for 6 months from October 2022 to April 2023 using a self-administered questionnaire by general dental practitioners registered in Nepal Medical Council. Knowledge and attitude about periodontics, various diseases and referral to specialist for special treatment were analyzed. Result Total of 238 General Dental Practitioners (GDPs) participated in this web-based questionnaire survey. Majority of general dental practitioners (GDPs) reported that they always performed full-mouth and subgingival scaling (193, 81.09%), providing advice on proper brushing techniques (205, 86.13%), advising patients to stop harmful habits (212, 89.07%), and offering diet counseling (122, 51.26%) for patients displaying signs of gingival or periodontal diseases. Majority of GDPs also indicated that they occasionally consult a periodontist for specific periodontal problems, such as the presence of periodontal pockets (143, 60.084%), mobile teeth (150, 63.025%), gingival enlargement (145, 60.924%), periodontal abscess (146, 61.344%), and gingival recession (149, 62.605%). Conclusion General dental practitioners play a crucial role as the primary point of contact for patients seeking dental treatment. The periodontal health of the general population largely depends on the knowledge, attitude, and practice of GDPs. KEY WORDS General dental practitioner, Periodontal referral, Periodontist
