The commonly used classification of aesthetic requirements into high, medium and low lip line may not serve the patient’s needs. Our suggestion is to consider every anterior case an aesthetic case regardless of the lip line. Fig. 16 Tooth socket after the atraumatic extraction. Fig. 15 A hopeless first upper premolar. Fig. 20 “Intra-external grafting” (inside and outside of the socket) with small Bio-Oss® particles (0.25 – 1 mm cancellous granules). In our experience, this grafting prevents resorption of the buccal bone plate and a subsequent concavity in the aesthetic zone. The particles are covered with a Bio-Gide® membrane.

This buccal angulation has two clinical advantages: firstly, it helps to avoid apical fenestration due to the natural morphology of the maxilla; secondly, it helps to achieve a correct emergence profile of the future crown if the implant platform is more buccally positioned. It is easier to create the correct prosthetic profile. > Dr. Tiziano Testori, MD, DDS, FICD, Via Rubini 22, 22100 Como, Italy phone: [phone], fax: [phone], e-mail: [email protected], web: www.implantologiaitalia.it > Dr. Matteo Capelli, DDS, Via Brera 28A, 20121 Milano, Italy phone: [phone], e-mail: [email protected] Treatment concept of Dr. Tiziano Testori and Dr. Matteo Capelli, I.R.C.C.S.

The membrane is intentionally left exposed in order to avoid any secondary mucosal approximation and to increase the amount of keratinised periimplant mucosa in a single procedure. 1.
