Simplified type 3 implant placement, after alveolar ridge preservation: a case study.

Alveolar ridge, after tooth extraction, could reduce its volume up to 50% in buccal-lingual width in the first twelve months and residual dimensions could interfere with correct three dimensional placement of implants and influence negatively treatment outcomes with regard to function and aesthetic aspects. Over the last decades, several approaches have been proposed and tested in order to prevent ridge volumetric contraction and provide maximum bone availability for implant procedure. This article presents a case study with a single anterior tooth replacement, illustrating socket seal technique followed by a type 3 timing implant placement. Immediately after tooth extraction, residual socket was grafted using Deproteinized Bovine Bone Mineral and a free gingival punch harvested from palate. After 3 months, a root-form titanium implant was inserted without additional regenerative procedures. Follow-up examination revealed favourable preservation of soft tissue width and height in the aesthetic area. Socket seal approach maximizes soft tissue healing, preserving ridge envelope and the subsequent implant placement, furthermore, results simplified, as any augmentation techniques are required. Clinical advantages of this method include predictable preservation of the soft tissues, favourable healing features, easy handling of graft materials and a positive benefit-cost ratio.
