Publication Crown Lengthening Surgery for Enhancing Restorative Treatment in Esthetic Zone(Kathmandu University, 2021) Dawadi, A; Humagain, M; Sapkota, B; Subba, M; Neupane, M; Lamichhane, SABSTRACT For obtaining adequate retention for restoring cases like subgingival caries or extensive caries that shortens the tooth, short clinical crown, and fractures, it is usually necessary to disclose more tooth structure. Crown lengthening procedure is done to increase the clinical crown length for restorative or esthetic reasons without breaching the biologic width. These procedures are also utilized to improve the appearance and retention of restorations placed within the esthetic zone. We report a case of crown lengthening surgery with an internal bevel gingivectomy which was done in our department without compromising tooth support and esthetics.

It is a benign tumor with slow-growing potential commonly affecting the anterior maxilla whose pathogenesis till date is uncertain. It is usually challenging to diagnose peripheral cemento-ossifying fibroma based on clinical observation and examination, hence histopathological examination is mandatory to arrive at an accurate diagnosis. Recurrence of the lesion is common unless and until it is completely excised. We present the report of two cases of peripheral cemento-ossifying fibroma of our department, complaining of a mass in the gingiva of posterior maxilla and mandible.

The sagittal root positioning and root angulation plays a vital role for case selection in immediate implant placement. Objective To evaluate, classify and compare sagittal root position between different maxillary anterior teeth. Method A 2-year retrospective study was conducted on 100 patients (53 males and 47 females) who fulfilled the inclusion criteria using cone beam computed tomographic images. The relationship of root of tooth to its alveolar housing were recorded as Class I to IV. In addition, the root angulation relative to the alveolar process was also measured. Result The sagittal root position (SRP) calculated on six maxillary anterior teeth on average was found to be 87.83% for Class I, 6.67% for Class II, 0.67% for Class III and 5.17% for Class IV respectively. The mean root angulation was found to be higher with canines on both side whereas lateral incisors had lesser mean root angulation. Root angulation of maximum teeth were between 10-20 degrees where immediate implant placement is possible. Conclusion Within the limitations of this study, the sagittal root positioning and root angulation in Nepalese population showed a favorable result for immediate implant placement. Maximum teeth were found to be close to the alveolar process with the exception of few teeth. KEY WORDS Immediate implant, Root angulation, Sagittal root positioning
