Summary:

The loss of alveolar ridge volume as a result of tooth extraction has been noted in the literature since the 1960s.1-3 The full extent of why this happens is still not entirely understood,4 with a widely accepted explanation for the loss relating to factors that include trauma the extraction socket as a wound sees upregulation of inflammatory processes, resultant activation of osteoclastic activity, resorption of the extraction socket, and an eventual healing that typically results in loss of tissue volume and architecture.5 Second, bundle boned removal of the tooth results in periodontal ligament (PDL) fibers being severed, loss of Sharpey fibers that insert into bundle bone, and a subsequent loss of the mineralized bone layer that lines the alveolus.4-6 At the buccal or facial aspect, the bone plate may consist entirely of bundle bone.

Implant Aesthetic Score for Evaluating the Outcome

Implant Aesthetic Score for Evaluating the Outcome
Implant restorations delivered according to the Brånemark protocol have proven to be highly predictable. To shorten the length of treatment associated with the Brånemark protocol, as well as to preserve soft and hard tissues, newer protocols have focused on reducing or even eliminating the time between tooth extraction and implant placement and between implant placement and prosthetic restoration delivery. The authors present a case in which control of postextraction implant placement, optimal implant…

The “Scalloped Guide”: A Proof-of-Concept Technique for a Digitally Streamlined, Pink-Free Full-Arch Implant Protocol

The “Scalloped Guide”: A Proof-of-Concept Technique for a Digitally Streamlined, Pink-Free Full-Arch Implant Protocol
Inadequate restorative space can result in mechanical, biologic, and esthetic complications with full-arch fixed implant-supported prosthetics. As such, clinicians often reduce bone to create clearance. The aim of this paper was to present a protocol using stacking computer-aided design/computerassisted manufacturing (CAD/CAM) guides to minimize and accurately obtain the desired bone reduction, immediately place prosthetically guided implants, and load a provisional that replicates predetermined tissue contour. This protocol can help clinicians minimize bone reduction and place the implants in an ideal position that allows them to emerge from the soft tissue interface with a natural, pink-free zirconia fixed dental prostheses.

Advanced Esthetic Management of Dental Implants: Surgical and Restorative Considerations to Improve Outcomes

Advanced Esthetic Management of Dental Implants: Surgical and Restorative Considerations to Improve Outcomes
This article demonstrates the importance of proper surgical and prosthetic principles in achieving esthetic implant results.Successful dental implant therapy in the maxillary anterior dentition requires meticulous attention to surgical and prosthodontic measures. Proper diagnosis, extraction technique, implant selection, and placement significantly impact outcomes. Respect of hard and soft tissue physiology following tooth loss and implant placement requires specific steps be taken. Management tissue contours properly, via regenerative therapy, results in successful framing of the restoration. Provisionalization and definitive restorative therapy also impacts the level of esthetic success.The contours of the temporary abutment and crown develop soft tissue contours for the final restoration. Overcontouring can lead to soft tissue recession and mucosal asymmetry. Design of the definitive crown(s) is crucial for long-term maintenance of esthetically acceptable results.

Partial Extraction Therapies: Science & Research Behind The Concept
The partial extraction therapies (PET) date all the way back to the 1970’s when the submerging of tooth roots aimed to preserve the alveolar ridge beneath full dentures. Today, the full scope of PET includes several, evidence-based techniques, that use the patient’s own tissues to prevent post-extraction ridge resorption. This lecture outlines a timeline of the research milestones that have occurred, past to present, that have established PET in our treatment milieu as we know it today.

Site Preparation & Osseodensification in Bone Management
Today's implant arena involves not only the understanding of procedures but also the science behind wound healing. Often new technologies and instrumentation evolves that have a significant impact on what we are able to do clinically. Piezosurgical devices, periotomes, osteotomes, hydraulic sinus devices, neurosurgical drills, and the "PET" (Partial Extraction Therapies) system are just a short list of those that have made surgery more efficient and less traumatic for our patients. Osseodensification is another concept that can be added to this long list. This lecture will speak about new age bone management concepts and how these technologies may be able to assist us. Potential issues and focus on use will be touched upon as well.

Bone Grafting & Implant Dentistry; Classification, Surgical Site Understanding & Membrane Selection Part 1 of 3
Once a tooth is extracted, the natural wound-healing cascade paired with irreversible alteration occurs. Hard tissue grafting techniques combined with the sound understanding of the surgical site theater will help the practitioner to make the proper decision in order to successfully treat their patient. The usage of biological modifiers and surgical barriers are proposed to assist in improving the predictability of the advance surgical care.
