Soft tissue augmentation at immediate implants using a novel xenogeneic collagen matrix in conjunction with immediate provisional restorations: A prospective case series.

Background: Collagen matrices used around immediate implants may reduce morbidity although there is limited evidence on their performance.

Purpose: To evaluate soft and hard tissue changes when combining immediate implants, hard and soft tissue grafting, and an immediate provisional restoration.

Material And Methods: In 12 patients, immediate implants were placed in the anterior maxillary and first premolar area together with a xenogeneic bone substitute.
