AOS (NSW) A/Prof Dale Howes - The Quest for Zero Defect – From Planning to Restoration Part 2


Dale Geoffrey Howes B.Sc. (Dent); BDS; M.Dent (Wits); FCD (SA) Pros; FICD.

Dale Howes has been recently been appointed Associate Professor in prosthodontics, School of Dentistry, Faculty of Medicine and Health, at the University of Sydney, Australia. He was previously in full time private practice with part time appointment as adjunct professor in the department Oral Rehabilitation University of the Witwatersrand before taking over as the Professor and Head of that Department.

He is the Immediate Past President of the ISMR (International Society for Maxillofacial Rehabilitation), board member and Treasurer of the ICP (International College of Prosthodontists)
He has received peer review fellowships from the Colleges of Medicine of South Africa and the International College of Dentists serving as the regional Vice Regent.  He is a past president of the Academy of Prosthodontics of South Africa, and founder member of the P-I Brånemark Institute of South Africa as well as the Face Value Foundation Trust, a Public Benefit Organisation.  This PBO is dedicated to enhancing head and neck treatment and rehabilitation through comprehensive multidisciplinary care, research and education.

He was also awarded the Premier Award of the South African Dental Association (2016) and the I.Y. Sendulskogo Commemorative Medal of the Russian Partnership of Head and Neck Oncology Specialists for outstanding achievements in medicine. (2015). He has Awarded Best Presentations at the Nobel Biocare World Congress 2005 and the Academy of Osseointegration Boston 2008.

He has lectured worldwide and supervised Masters and PhD projects, been external examiner nationally and internationally as well as publishing research and book chapters in fields including head and neck cancer rehabilitation, occlusion and biomechanics.

He has developed innovative implant fixtures, components and protocols to solve hard and soft tissue constraints facilitating screw retained implant prostheses optimising patient management in the regular implant patient as well as for the patient compromised by head and neck trauma and cancer.

Please note:  Due to COVID-19 the Half Day meeting has been rescheduled to a webinar.  

"The Quest for zero defect – from planning to restoration" Part 2

"The straight line belongs to man; the curved line belongs to God"
(Antoni Gaudi)

The human alveolus is an intricate, nonuniform structure that encases the complex anatomy of the human dentition and critical anatomic structures. These bony constraints are complicated by those within the teeth, particularly the anteriors, which display a significant subcrestal disparity between root and crown angulations imposing serious challenges in implant dentistry.

To overcome these anatomic constraints of the teeth and their alveoli, particularly after post-extraction resorption, the implant surgeon is often placed on the horns of a dilemma between the ideal prosthodontic position and angulation vs surgical compromise or visa versa.

Most practitioners concede that screw retention of implant supported prostheses is preferred as it allows for ease of retrieval during prosthetic and surgical maintenance. Enabling screw retention requires meticulous surgical planning and skill to position the fixture within bone as well as providing for the prosthetic needs of screw retention.

This lecture will outline the crucial aspects of anatomic constraint complicating implant placement and rehabilitation as well as the obstacles and complications introduced by the commonly used solutions used for supracrestal angular correction, such as the angulated screw channel (ASC).  We will explore the concept of subcrestal angle correction to overcome these constraints and reduce the need for alveolar augmentation facilitating screw retention, as well as innovative implant designs for immediate placement and loading for the anterior maxilla which are rapidly achieving the requisite evidence.


Learning outcomes:

At the end of this lecture, the participant should be able to:

1.                Evaluate the implications of the anatomic constraints of the facial skeleton on implant dentistry.

2.                Analyse the implications of contemporary supracrestal angle correction techniques used in implant dentistry

3.                Appraise the advantages of subcrestal angle correction for screw retained implant supported prostheses.

4.                Apply the principles of subcrestal angle correction to all intraoral implant zones and prostheses.

5.                Understand the design principles of implants used for anterior immediate placement and loading.
