Aesthetic Rehabilitation Of A Complex Crown-Root Fracture By Fragment Reattachment With A Fiber-Reinforced Post: A Case Report, Sarra Saidi, Meriem Fejjeri, Mahdi Tlili, Sabra Jaafoura, Nadia Frih

International Arab Journal of Dentistry

Complex crown-root fractures are characterized by the involvement of both crown and root with pulp exposure. They pose aesthetic, functional, and psychological problems for the patient. Furthermore, they can pose technical difficulties for the practitioner. The purpose of this case report is to describe the management of a complex crown-root fracture of the right upper central incisor with subgingival limit by reattaching the tooth fragment with fiber-reinforced post. We considered a coronal elongation (gingivectomy and osteoplasty) to recreate the biological space and to expose the limit of the fracture line to guarantee the quality of the bond.

Implant Overdenture Abutment Loosening Under Hyperbaric Conditions, Zana Jamal Al-Saloum

Graduate Theses, Dissertations, and Problem Reports (ETD)

Objectives: To investigate the effect of various hyperbaric air pressures on the loosening of LOCATOR® (ZEST Anchors, LLC, Escondido, CA USA) overdenture abutments.

This study aimed to evaluate the learning outcomes, accuracy, efficiency, and user perceptions of two dynamic navigation systems, X-Guide and IRIS-100, in implant placement training for novice dentists across varying anatomical complexities.Fourteen novice dentists were initially recruited, with 12 completing the full training program. Participants underwent implant placement training on models representing straightforward and advanced cases using two training sequences: X-Guide followed by IRIS-100, and IRIS-100 followed by X-Guide. Accuracy was assessed by measuring angular, coronal, and apical deviations, as well as operation time, across pre-test, post-test 1, and post-test 2 phases using the freehand technique, followed by repeated measures …

Inflammatory Responses Of Peri-Implant Crevicular Fluid On Different Dental Implant Abutment Materials After 6-Months Functional Loading: A Randomized Clinical Controlled Trial, Penkamol Wongrattanapasson

Chulalongkorn University Theses and Dissertations (Chula ETD)

Different abutment materials induce different immune responses in peri-implant soft tissues. Previous study showed that Ti base abutments without loading demonstrated comparable soft tissue-reaction to titanium abutments (Sampatanukul et al., 2018). Inflammatory responses after functional loading had not been elucidated in the previous study. This study investigates the inflammatory responses of peri-implant crevicular fluid around two abutment materials; titanium and titanium base (Ti base) after 6-months functional loading and identifies suitable abutment material which can induce stable inflammatory response in the peri-implant soft tissue. Sixteen implants of either Neodent or Straumann single implants were placed in sixteen patients in anterior …

Journal of Dentistry Indonesia

The diagnosis and prognosis of teeth with endo-perio lesions present a major challenge for dentists. Proper diagnosis is critical in determining treatment and the long-term prognosis. However, treating complex endodontic and periodontal lesions is one of the most common challenges in current clinical practice. The coexistence of pulpal and periodontal tissue damage may complicate diagnosis and further influence dental prognosis. This article consists of a case report evaluating the efficacy of xenografts and resorbable membrane pericardium in treating bifurcation lesions associated with periodontal lesions of the left mandibular first molar. A 22-year-old female patient was referred by conservative dentistry with …
