SPEAKER PROFILE (DAY 3)

Dr. Ben Ng
BDS (OSM), AdvDip (Osseointegration Implant Modality for Oral Maxillofacial Rehabilitation),
FICOI, FICD, FITI
Dr. Ben C. Ng graduated with B.D.S. in 1980 from Osmania University. He completed
Comprehensive Course on Osseointegrated Implant Modality for Oral and Maxillofacial
Rehabilitation using IMZ implants in 1990 from Institut Friedrichfeld AG, Manheim,
Germany and obtained an Advance Diploma in Implant Dentistry. Dr. Ben C. Ng was
conferred as Fellow of International Congress of Oral Implantologist in 1996. Continuing his
passion towards implantology, he became the Conferred Fellow of the International Team
of Implantologists in 2006. He also became the Conferred Fellow of International College
of Dentistry in 2013.
Moreover, Dr. Ben C. Ng has been appointed as Director for International Team for
Implantology (ITI) Study Club since 2010. He is also the Founding Member/Council Member
of Malaysian Oral Implant Association and a Life Member of Malaysian Dental Association.

Lecture 1 : “Narrow Ridge? - No Worry, Here Comes the
Alternative” - Reshaping the Future of Implant
Dentistry
The progressive resorption of the alveolar ridge after tooth extraction may lead to maxillary
or mandibular atrophy, resulting in reduced horizontal or vertical dimensions of the
bone crest or in a combination of them. Insufficient bone volume could compromise the
implant insertion. Implant stability plays an important role in the osseointegration of dental
implants. 4 decades ago, blade implants showed a high failure rate due to unpredictability
in achieving primary stability, the type of loading protocol and postoperative complications.
Then about 12 years ago, emerges the use of wedge implants which can be considered as
a valid minimally invasive surgery technique in atrophic bone crests, where the insertion
of traditional implants without bone regeneration procedures cannot be done. The wedge
implant represents an interesting evolution of the Linkow blade.

In the study of Vercellotti et al, a good primary stability was obtained after the insertion of
wedge implants in all cases and both mesio-distal and bucco-lingual ISQ values at 6-month
follow-up resulted in significantly higher than at 4-month follow-up. These implants showed
low morbidity and positive short-term clinical results in narrow ridges treatment. From the
data obtained, these implants demonstrate an excellent prognosis, avoiding complications,
facilitating the surgery and improving the patient’s comfort.
Moreover, the possibility of preparing the implants site with cold-cut vibrating inserts rather
than with high-speed drills, reduces the heat avoiding the risk of creating bone necrosis
and favouring better osseointegration. A recent meta-analysis showed that ultrasonic
implant site preparation has a positive influence on early bone healing, resulting in faster
development of secondary stability when compared to conventional drilling techniques.
This presentation will demonstrate the insertion of a new wedge-shape dental implant, in a
patient with a horizontal bone width between 3.80mm and 4.10mm.

Lecture 2 : “How Do You Know Your Implants Are Ready to be
Loaded?”- Guessing?
Dental implant treatments have evolved over half a century and are practically successful
and safe. On average, we believe more than 90% are successful. But that average success
rate may or may not hold true for each patient, each implant and each case; so success is
not guaranteed! Of course, a failed dental implant can be agonising for the clinician involved
and traumatising for the patients . With today’s new and innovative techniques, reductions
in treatment times and opportunities for patients with risk factors to have successful implant
therapy have improved significantly and are acceptable. But correctly assessing implant
stability and osseointegration is still a challenge to the clinicians. Many methods have
been advocated and developed over time. The assessment and measurement of implant
stability depends on several factors. Using the latest tool or device to establish good implant
stability has gained much attention and usage among clinicians who want to achieve long-
term predictable outcomes. This presentation deals with the understanding of the basis of
