Immediate Implant Placement Using the Socket Shield Technique in Maxillary Esthetic Zone

Официальное название

Evaluation of Immediate Implant Placement Using the Socket Shield Technique in Maxillary Esthetic Zone (Clinical and Radiographic Study)

Обзор

Immediate implant placement in the esthetic zone is an approach that helps preserve soft and hard tissue architecture. However, post extraction bone resorption is still a significant challenge. The socket shield technique (SST) has emerged as a promising way for preserving the buccal plate, potentially improving implant stability and reducing radiographic bone loss. The aim of the present study is to evaluate the clinical and radiographic outcomes of the socket shield technique in the maxillary esthetic zone by assessing implant stability, radiographic bone loss as well as esthetic outcome over a specified follow-up period.

Вмешательства

• Процедура Socket shield concept and immediate implant placement
  Tooth Sectioning: The tooth will be sectioned mesiodistally using a fissure bur, preserving the buccal segment. Palatal fragment extraction: carefully after sectioning the tooth , the palatal fragment is luxated and extracted with the most important factor is taking care of the buccal part not to become loose , the extraction is done using a periotome to be minimally invasive and to preserve the bone from major damage. Shield Preparation: The buccal fragment is reduced to bone level using a ro

Критерии участия

Критерии включения

• Patients with a non-restorable maxillary tooth in the aesthetic zone indicated for extraction and subsequent immediate implant placement.
• Patients with extraction socket Type I.
• A good standard of oral hygiene.

Критерии исключения

• Patients with extraction socket Type II or III, with defect in the buccal plate.
• Absence of at least 2 mm bone apical to the extraction socket, necessary to obtain adequate primary stability for the implant assessed by pre-operative radiographic evaluation.
• The presence of any local factor that may interfere with extraction as tooth ankylosis.
• Patients with deciduous teeth.
• Patients with bruxism
• Heavy smokers.
• Systemic conditions that are considered as a contraindication for placement of implant or those that may interfere with wound healing and immunocompromised conditions and uncontrolled autoimmune diseases.
• History of oral or intravenous bisphosphonate therapy or any treatments with other medications that may interfere with bone metabolism within the past 12 months.
• Patients receiving radiotherapy or chemotheraphy.
• Patient with active infection or chronic infection with severe bone loss.
