Maxillary Molar Extraction Technique: Decoronation and Sectioning
This short video reviews two cases to demontrate a Maxillary Molar Extraction Technique using Decoronation and Sectioning.
Maxillary molar extractions can often be difficult, as the maxillary molars have 3 roots which are divergent. This poses a challenge to extracting the tooth hole without damaging the surrounding bone and soft tissue. One strategy that works well is the divide and conquer method: First you decoronate the tooth and then aftewards you split the roots into individual roots and take them out one by one, thereby perserving the surrounding architecture. <sup>1</sup>. This short video shows 2 cases where this method was employed for a successful extraction. In the first case, Tooth #14 was deemed hopeless and was extracted. Notice in this case how there was no need to raise a flap for extraction of the tooth. In the second case, Tooth #3 with an old root canal, the extraction was followd by an immediate implant. An interesting tip provided in both cases, is to "recreate" the tooth following extraction to make sure that all of the components were properly removed.
