tiens puisque tu parles d'études, il y a une étude qui compare la technique classique et au piezo et montre que c'est pas plus long avec le piezo.

Une bonne technique c est une technique facile a utiliser par un mec bras-cassé ( genre membrane non resorb Vs DMA).
Apres si toutes les techniques sont compliqué c est quelles sont toutes pourries, ou toutes bien...

Le problème c'est que le mec bras-cassé s'est pas toujours gérer les complications. Alors peste ou choléra ?

Cher Jean Yves, un coup de Medline et on peut y trouver :

Simplified procedure for augmentation of the sinus floor using a haemostatic nasal balloon. Muronoi & al

Division of Oral Pathology, Tohoku University Graduate School of Dentistry, Sendai, Japan.

Perforation of the sinus membrane is the most common complication of sinus lift augmentation. A haemostatic nasal balloon can easily separate the sinus membrane without perforating it. The use of a haemostatic nasal balloon has three major advantages: a low risk of perforation of the sinus membrane even in anatomically complex conditions, a low incidence of infection and bleeding, and a shorter operating time.

Une technique dérivée de la technique d'élévation de la membrane sinusienne par ballonnet est la MIAMBE qui est alors à comparer la technique de Summers. Là aussi dans Medline on peut y trouver :

Minimally invasive antral membrane balloon elevation: report of 36 procedures. Kfir & al

Division of Orofacial Pain, New Jersey Dental School, University of Medicine and Dentistry of New Jersey, Newark, NJ 07103, USA.

BACKGROUND: The posterior maxillary segment frequently has insufficient bone mass to support dental implants. This registry evaluated the feasibility and safety of minimally invasive antral membrane balloon elevation (MIAMBE), followed by bone augmentation and implant fixation. METHODS: Thirty-six consecutive patients referred for posterior maxillary bone augmentation underwent alveolar crest exposure and implant osteotomy followed by MIAMBE (> 10 mm). Fibrin and bone particles were injected beneath the antral membrane, implants were placed into the osteotomies, and primary closure was executed at the same sitting. RESULTS: All 36 patients successfully concluded the procedure with no significant procedural complications or discomfort. Procedure time was 48 +/- 15 minutes. Incremental bone height consistently exceeded 8 mm, and implant survival of 97% was observed at 6 to 8 months. CONCLUSIONS: MIAMBE resulted in high procedural success and satisfactory bone augmentation implant survival and complication rates. Because it is minimally invasive, this procedure may be an alternative to the currently used surgical methods.

Minimally invasive antral membrane balloon elevation followed by maxillary bone augmentation and implant fixation. Kfir & al

Dental Clinic, Hanesihim Street 40, Petah-Tikvah, Israel.

The posterior maxillary segment frequently suffers from insufficient bone mass to support dental implants. Current bone augmentation methods, including the lateral maxillary approach (ie, hinge osteotomy) and sinus elevation by osteotome, have many shortcomings. The objective of our study was to assess the safety and efficacy of minimally invasive antral membrane balloon elevation (MIAMBE) followed by bone augmentation and implant fixation (executed during the same procedure). Alveolar crest exposure and implant osteotomy were followed by sequential balloon inflations yielding > 10 mm MIAMBE. A mix of autologous fibrin and bone particles with bone speckles was injected beneath the antral membrane. Implants were fixated into the osteotomies, and primary closure was performed during the same sitting. A total of 24 patients were enrolled. Successful conclusion of this procedure was accomplished in 91.6% of the initial 12 patients and 100% in the second dozen cases without significant complications. Patient discomfort was minimal. Long-term follow up revealed satisfactory bone formation, resulting in adequate implant stability. We conclude that the protocol of MIAMBE results in an excellent success rate, low complication rate, minimal discomfort, and long-term safety and durability. Because it requires only basic equipment and a short learning curve, this clinical approach should be widely employed.

Bonne lecture. Amicalement
