Abstract:

Reconstruction of the atrophic maxilla can be challenging due to inadequate quantity and quality of bone often requiring time consuming and costly grafting procedures which can dictate up to a one-year delayed loading protocol.
An accelerated treatment protocol with immediate function can be made possible with the use of remote skeletal anchorage using the Pterygoid process of the Sphenoid bone.
This in-depth Pterygoid theory workshop will focus on the up till now relatively under-evaluated and under-used Pterygoid implant.

The “how and why” of pterygoid implants will be addressed in detail viz:

1. relevant surgical anatomy, 
2. indications and contraindications 
3. step-by-step surgical technique
4. mistakes, problems & complications 
   The value of full graft resorption and healthy host bone will be discussed along with a longer-term case assessment to show these benefits.

Osseodensification is an evidence-based approach to implant osteotomy preparation that enhances implant stability and bone density without compromising healing. This lecture will present the biomechanical, histological healing timeline, and clinical data of Osseodensification. It will discuss bone plasticity and its clinical effect and will also cover the clinical versatility of this novel technique including Sub-Crestal Sinus Auto Grafting, Ridge Expansion, Immediate Implant Placement with Osseodensification, and Guided Expansion Graft. Several clinical protocols will be outlined.
Recent research from the wider medical community on Calcium Phosphates offers a new explanation showing how these materials up-regulate host bone regeneration with their osteoinductive potential. 
When considered in combination with a new strand of research into osteoimmunology, dental implantology gives a much clearer understanding of the host response to foreign body placement, healing and the reason why some graft materials appear to work more quickly than others.
During this seminar, the speaker will examine this research, among other research on the topic in recent years, to show the concept of true host bone regeneration and the importance of using resorbable materials due to the inherent risks of residual graft remaining in the site long-term.
These concepts will be demonstrated with clinical cases from the speaker’s experience, examining the surgical protocols to optimize outcomes.  Cases will include routine bony defects, large-scale full-arch regeneration, socket grafts, sinus augmentations, perio defects, peri-implantitis and apicectomies and cyst site regeneration.  The speaker will demonstrate a variety of delayed and immediate placements with long-term follow-ups.

Introduction:

Osseodensification is a groundbreaking technique in the field of dental implantology that has revolutionized the way in which implant osteotomies are prepared. In traditional implant placement, drills are used to prepare the bone to receive the implant. However, when using drills, the cutting forces can lead to necrosis of the surrounding bone tissue. In contrast, Osseodensification uses specially designed burs, which densify and condense the bone without removing its structure, leading to the creation of a more stable implant site. This technique not only improves osseointegration but also provides an increase in implant primary stability. Osseodensification takes advantage of the natural bone plasticity. This technique leads to faster healing and greater bone-to-implant contact (BIC), improving implant success rates. Moreover, Osseodensification can be used in a wide range of clinical situations, such as sinus floor elevation, ridge expansion, and immediate implant placement, making it a versatile treatment option for clinicians. Overall, Osseodensification provides an innovative and clinically effective solution for dental implant placement that enhances implant stability and reduces complications, providing a more predictable and successful outcome for patients.

Learning Objectives:

At the end of this workshop participants should be able to:

• Have a good understanding of the relevant surgical anatomy for placing Pterygoid implants
• Execute step-by-step the workflow for Pterygoid implant placement
• Recognize and prevent incorrect Pterygoid implant placement & complications.
• Evaluate the effectiveness of Osseodensification in improving implant stability and bone density compared to traditional implant placement techniques.
• Differentiate the clinical versatility of Osseodensification in various implant placement procedures, such as Sub-Crestal Sinus Auto Grafting and Ridge Expansion.
• Construct a clinical protocol for the optimal utilization of Osseodensification in the implant placement sequence.
• Analyse the biochemical and histological healing timeline in Osseodensification compared to traditional implant placement techniques.
• Implement the proper diagnostic criteria necessary for selecting patients who can benefit most from Osseodensification in implant placement.
• Have a knowledge of how the bone remodels
• Looking at why using Alloplastics to generate the hosts own bone around implants and the patient’s own teeth can lead to better stability and results.
• Explain and recognise techniques for gaining the best results.
