Lecture Summary
It is of utmost importance to diagnose peri-implant mucositis and peri-implantitis at an early stage in order to intercept with supportive therapy to arrest existing infections. As diagnostic test parameters from the periodontal field appear reasonable to be used. Among those, peri-implant probing test, presence or absence of bleeding upon probing, suppuration and radiographic evaluation can be recommended. Implant mobility, however, constitutes a highly insensitive but highly specific sign of a complete loss of osseointegration leading to the loss of the implant. Increased probing depth and consistent bleeding on probing have been demonstrated to have reasonable diagnostic accuracy for the discovery of peri-implant lesions. Since peri-implant lesions represent opportunistic infections their therapy must be based on infection control. Under these conditions progression of the disease may be arrested and subsequently, lost peri-implant tissues may be regenerated by surgical procedures. In this context a treatment approach for peri-implant mucositis and peri-implantitis termed Cumulative Interceptive Supportive Therapy (CIST) has been propagated and validated in clinical studies. Under the CIST concept mechanical debridement and antiseptic cleansing will be followed by the application of antibiotics depending on the diagnosis of the peri-implant tissues, specifically absence of presence of bleeding on probing and probing pocket depth will be used to cumulatively add one regime to another if the conditions appear to be worth.

The 2nd Study Group
We are pleased to report that our 2nd study group was successfully held on 22nd July 2010. Despite the black rainstorm warning signal was issued during that evening, our moderators telephoned the participants, all of them decided to come and continue with the meeting. Although 2 of them did not actually make it to reach the venue, we are deeply impressed by the enthusiasm and support from our members. Eventually we have spent a fruitful night discussing on various aspects of implant treatment on periodontally susceptible patients while heavy rain continued to pour outside.
Thank you again to all the participants. For those who could not come due to the bad weather, the registration fee will be returned. We are looking forward to see you in the coming events.

Lecture Outline
Periodontal diseases are the most commonly occurring diseases yet unusual infections in humans. They are one of the most important global oral health burdens. A recent WHO report shows that severe periodontitis exists in 5‐20% of adult populations worldwide, and most children and adolescents exhibit signs of gingivitis (Petersen et al. 2005). Periodontitis remains a major cause of tooth loss in adults. Currently, periodontal diseases are also recognized as serious infections with profound effects on general health. In daily dental practice, patients with moderate to advanced periodontitis usually present with a wide range of oral problems. Individualized preventative measures and comprehensive treatments are great challenges to general dental practitioners. It is evident that periodontal care is a fundamental component of general practice. Without appropriate screening, risk assessment and effective control of periodontal infections, other dental treatments can be greatly compromised or ultimately fail. In recent years, an increasing number of dentally‐related law‐suit cases arise either from periodontal negligence litigation or poor clinical management outcomes. Over the past two decades, there is a substantial progress made in understanding the nature of periodontal diseases and in developing various innovative approaches in periodontal practice. This advance provides great challenges and exciting opportunities for dental practitioners in management of periodontal diseases through teamwork and collegiality.
The 1st Global Congress of Chinese Dentist was held from 1-4/12/2010 in Xiamen China. Thanks to the sponsor from Hong Kong Dental Association, seven of our council members had attended the meeting. We are glad to be part of this historic event and be able to meet our colleaques from different parts of China as well as from many other parts of the world in this wonderful congress.

Abstract:
This lecture is designed to help dentists in dealing with common implant complications, in particular avoiding complications before occurrence. Basics of treatment planning concepts, the mechanism of bone loss and the implant failure ( biological, biomechanical and the combination) will be addressed and the prophylactic as well. The treatment for implant d i s e a s e s / c omp l i c a t i o n s i n c l u d e s : chemotherapeutic agents, apically positioned flap with or without implantoplasty, implant surface detoxification, guided bone regeneration, soft tissue grafts, implant removal as well as re-implantation. A decision tree in managing the peri-implantits will also be presented.
