The window approach for extraction of tooth root fragments: a different soft tissue management [PDF]

open access: yes, 2018
Different techniques have been proposed for the removal of the apical portion of fractured teeth. The window approach was proposed in the past to remove a tooth root fragment through a buccal bone opening at the level of fragment.

Management of post‐implant fibrous dysplasia in the maxilla: A case study

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Fibrous dysplasia is generally rare, and even rarer in older adults. Special care is needed when altering the alveolar bone in these cases, especially if an implant is involved. This case study highlights such a scenario. Methods This case study details the experience of a 63‐year‐old African American female who presented with a ...

Biologically‐oriented alveolar ridge preservation to correct bone dehiscence at immediate implant placement

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background The purpose of the present case study is to describe the application of a modification of the Biologically‐oriented Alveolar Ridge Preservation (BARP) principles in cases of peri‐implant bone dehiscence (PIBD) due to a compromised alveolus at immediate implant placement (IIP).
