简要总结
patients with fractured teeth in the esthetic area requiring immediate restoration will be recruited to the study. Immediate implants will be placed and patients will be restored either with straight or angled abutments. Implant failure will be measured.
详细描述
A: General operative procedures:
The study will be explained in details to the eligible participants with all possible alternative treatment options and possible risk.
If a patient accepts the treatment, informed consent will be signed. Standard extra oral and intraoral examination will be carried out. Diagnostic charts will be filled including medical and past dental history.
The patient will choose a sealed envelope to determine the allocation group. Preliminary impressions will be taken. The tooth to be extracted will be trimmed from the cast and an ideal wax up will be done.
A hard vacuum stent 2 mm thickness will be constructed over the cast with the wax up for fabrication of the temporary crown later.

入选标准
- •Patients with teeth or remaining roots indicated for extraction in the esthetic zone and eligible for immediate implant placement Sufficient bone labially (at least 1.5-2 mm) assessed after cone beam computer tomography (CBCT) scan Presence of adequate mesio distal length between the adjacent natural teeth (at least 7 mm), measured on the study cast Presence of adjacent natural teeth to the tooth/teeth to be extracted
排除标准
- •Presence of active signs or symptoms of acute infection in the tooth or the remaining root Heavy smokers (more than 2 packs per day) Parafunctional habits (clenching or bruxism) diagnosed by history taking and observation of the occlusal surface of the posterior teeth for wear facets Patients with poor oral hygiene Pregnant women Any systemic condition that may interfere with osseointegration (as uncontrolled diabetes, recent head and neck radiation) Severe overeruption of the opposing teeth to avoid any premature contact with the temporary crown during the osseointegration period.
