Abstracts
Why hesitate to use micro implants? Hee-Moon Kyung
Control of anchorage is one of the most important aspects of orthodontics. Many traditional treatment protocols have incorporated both extraoral (headgear) and intraoral (inter-maxillary elastics) approaches to maintain anchorage. Unfortunately, patient compliance often is considered the “Achilles heel” of controlled tooth movement. In an effort to maximize anchorage while reducing the dependence on patient cooperation, micro implants are commonly used in these days. However, many doctors especially including orthodontists are still hesitate to use them because of the side effects, such as root injury, infection and ankylosis etc. during and after placement of micro implants.
Topic to be covered in the presentation includes the micro implant surgical procedures, the way for avoidance of complications, proper selection of micro implants, and some case reports.
Is all that they say about the orthodontic Micro implants true ? Relating evidence to clinical reality? - Anmol S Kalha
The advent of the orthodontic micro implant has been hailed as one of the most significant advances set to expand the boundaries and horizons of clinical practice. While the literature is replete with studies on the implants, the clinician is still perplexed if this would really fall within the realm of a busy practice. Do they really work, how easy is it to place and remove them , how should they be placed , do they fail ? are there any potential hazards of implants ?
It is easy to look at all these perspectives from the point of the quick courses or in Guru driven orthodontics , the eventual sustainability of any such innovations will be based on science and evidence. This presentation will try and review the existing evidence to support or contradict facts on the use of micro implants and would also provide evidence based clinical tips to integrate micro implants into a busy clinical practice.
Micro screw Implant Anchorage;
Most Challenges are the use of ‘Right Biomechanics’ rather than screw retention!
- Mani K. Prakash
In the years gone by, the most time and thought that used up in treatment planning a complex case could be attributed to one single factor called ‘Anchorage Management’. This is was even more dominant in extraction cases as well as those one that had vertical deviations. Every competent clinician not only spent whole lot of time before the commencement of the treatment, also during the course of correction changed modes to fulfill the anchorage dictates. In spite of the fact the operator used several anchor conserving methods to obtain adequate treatment objectives, more often then not the treatment course ended up going astray resulting in loss valuable treatment time and compromised objectives. The orthodontic tenure then was not all that honky dory!
The renaissance in this uncomfortable way of life was heralded by arrival of Micro Screws. They were god’s great gift due to their small size, greater number of sites for placement, varied indications, simpler surgical placements with no pin pricks for infiltration anesthesia, easy to deliver forces from and uneventful removal. No lab work was involved with reasonable cost incurred.
Current clinical method have amply demonstrated that insertion and retention of the screws in the mouth for the required time for the needful applications is no more an issue. Some of key factors concerning screw retentions, like root proximity, bone density etc. have been addressed reasonably well to increase it’s stability.
The treatment planning protocols does have to take into consideration the ease with which one could translate groups of teeth in any required direction, with no reaction on any other teeth. This opens a window of opportunity for a plethora of options like-Reduced treatment time (as no concern for any mesial movement of molars), Closing difficult open bites, Major space closures, Reducing the surgical options in those border-line surgical cases, Use of third molar extraction spaces for Distalizing buccal segments efficiently –so far considered as a futile exercise!
Now the real challenges lie in the correct use force systems to optimize needful movements in the three planes of space. The forces and resultant moments are a little bit different compared to conventional mechanics. One has to realize the fact that in the implant driven systems, they become the pall bearers of the anchor forces and not the molars, as in conventional orthodontic force methods. Then the whole biomechanics is a different ‘ball game’.
These factors will be discussed with interesting spread of relevant case reports and clinical indicators.
