Sinus floor elevation is a predictable procedure when placing implants in the atrophic posterior maxilla. Several techniques were described in order to access the maxillary antrum and safely elevate the sinus mucosa. Piezoelectric bone surgery is currently considered a state of the art tool when performing sinus floor elevations. Because of their accurate micrometric and selective action, piezoelectric inserts perform precise and safe bone cutting of the buccal sinus bone and prevent sinus mucosa perforations. During this course, we will review surgical anatomy and present radiographic assessment advantages in order to detect anatomic risk factors and rule out pathologic conditions that may jeopardize the final surgical outcome. Latest advances in both lateral and crestal sinus floor elevation surgical techniques will be presented and the importance of new advances and technologies, such as the use of piezosurgery, will be exposed. Management and prevention of complications will be lastly developed and long-term clinical and radiographic follow-up will be explained. At the end of the theoretical part, participants will have the opportunity to exercise their practical skills on animal models. The efficiency and evolution of piezosurgery inserts will be tested on eggs model. Lateral and crestal sinus floor elevation techniques using new, safe and efficient, piezoelectric inserts will be performed on lamb models.
Overcorrection is the requirement to obtain a lot more expansion than what is ultimately necessary because we know that most part (up to more than 50%) of the gains obtained with the expander will be lost.
The following image illustrates a transverse cut of the palate where a crossbite is present on the right side. (A) Unilateral posterior crossbite (blue circle on the patient’s right side). The opposite side can be normal (no crossbite) or could also present a crossbite (bilateral crossbite). (B) As expansion progresses, teeth are moved outward. Interference between the tips of the teeth may occur on the side where the crossbite was; the teeth will then momentarily fit in a tip-to-tip relationship (red circle). On the opposite side, teeth may separate vertically (absence of contact). The patient may then be under the impression that teeth only touch on one side. The interference may sometimes be adjusted by polishing the tips of the teeth if this causes discomfort to the patient. (C) At the end of expansion, overcorrection that makes the upper teeth “go over” the lower teeth is seen on each side (more on the side where there was no crossbite to begin with). This is normal and desirable. (D) Normally, after the relapse following the removal of the appliance, the overcorrection disappears and teeth touch normally after having returned partially toward the middle.

10 veneers. Hmmm I wonder if she likes her new smile makeover. Thank you for being an amazing person and joy to work with @katchirish . A positive attitude and skillful execution is all that’s needed.
