简要总结
The objective of this randomized controlled clinical study was to compare bone quality between three different alveolar ridge preservation methods, also with the evaluation of primary and secondary dental implant stabilities at these sites.
详细描述
In the present study will be collected 24 patients, with indication of extraction of premolars or upper incisors. All participants will sign a Free and Informed Consent Form (TCLE), agreeing to participate voluntarily in this research.
Patients were randomly allocated into three groups according to the following treatments:
Group RET: Closure of the alveolus by first intention through palatal flap sliding according to the technique of Khoury.
SBC Group: Fill bone alveolus with Bone Ceramic® graft (Straumann AG, Basel, Switzerland) and cover it with palatal flap according to the technique of Khoury.
PRO Group: Alveolus sealing by a temporary ovoid pony of acrylic resin.
