Management of the Hard and Soft Tissue Changes Following Tooth Extraction for Improving Implant Dentistry

Mauricio Araujo, DDS, MSc, PhD

The management of the ridge alterations that take place following tooth extraction is of great interest for implant dentistry. The current presentation will describe a series of studies regarding the various ways to approach the post-extraction bone diminution. It will be demonstrated that the anatomy of the alveolar process influences the amount of post-extraction bone loss. The benefit of a minimally invasive tooth extraction for the socket healing will also be discussed. The use of ridge preservation, a clinical procedure that aims at preserving the ridge volume within the envelope existing at the time of extraction, and ridge augmentation, a procedure that aims at increasing the ridge volume beyond the skeletal envelope existing at the time of extraction, will be described. Clinical cases that illustrate the surgical technique and outcome of ridge preservation and augmentation procedures will be discussed.


9:00 – 9:45 am

Grafting the Esthetic Zone for Implants

Waldemar D. Polido, DDS, MS, PhD

Numerous details are indispensable to achieve an excellent esthetic result in implant dentistry. Among them is the increasing need for bone and soft tissue augmentation in the esthetic area, in both vertical and horizontal aspects. However, these grafts can be applied at different moments of the treatment, according to the clinical situation. Immediate or delayed implant placement, socket preservation procedures and staged grafts and implant placement are the possible choices to rehabilitate the esthetic zone.


10:15 – 11:00 am

Dense Bone Protocol: How to Achieve Viable Type 2-3 Bone Using Xenograft and Resorbable Membranes

Alan M. Meltzer, DMD, MScD

Many therapists feels that viable high quality non-granular bone is difficult to achieve with xenograft on a predictable basis. A step-by-step protocol will be presented using xenograft and collagen to achieve consistent outcomes. Human histology will be presented. Topics to be covered will include:

  • Defect classification
  • Membrane classification
  • Flap design including special extraction techniques
  • Site preparation
  • When to delay implant placement and when to immediately place
  • Graft preparation and graft placement protocol


11:00 am – 12:00 pm

Designing a Connective Tissue Graft Alternative from Scratch: Perspective From Prototype to 3-Year Clinical Follow-up

Daniel Thoma, DMD

Recent clinical data underlined the importance of a sufficient mucosal thickness to provide healthy peri-implant tissues and favorable esthetics. A newly developed volume-stable collagen matrix provides similar outcomes with respect to soft tissue volume but is associated with less morbidity and complications than autogenous grafts, thereby offering significant benefits for patients and clinicians.
