A8 Dental Tribune U.S. Edition | February 2013 CLINICALINDUSTRY NEWS Ad Safe, accurate, simplified sinus-lift technique for general practitioners In Part 1 of this three-part series, published in the November 2012 Dental Tribune U.S., we presented a sinus lift technique involving hydraulic pressure to elevate the floor of the maxillary sinus. Many respected clinicians and researchers have taken the task to com- pare the effects as it is related to a percent- age of sinus perforation using existent in- tracrestal sinus lift techniques. These proven surgical techniques include the use of osteo- tomes (Summers — and its multiple varia- tions), balloon lift, hydraulic sinus condensing technique (Chen and Cha) and motor-driven drilling systems. Scientific articles published in 2012 by Loma Linda School of Dentistry (Garbacea and Lozada ) and the Department of Periodontics and Oral Medicine, Univer- sity of Michigan School Dentistry (Chan and Avila), assessed crestal sinus floor elevation using cadaver heads and endoscopes to study the incidence of maxillary perforations. Both studies concluded that perforations can oc- cur with any technique but are more likely to happenwhenthemembraneisraisedpastthe 10-mm mark measured from alveolar crest. A recent prospective study published in 2012 by the Division of Prosthetic Dentistry, Maxillo- facial Unit in Sweden (Fornell and Johansson) presented a CBCT-guided osteotome sinus el- evation technique that shows improvement over conventional techniques in that there is decrease in the percentage of perforations. The purpose of this article is to introduce a surgical technique that combines planning and drilling using CAD/CAM surgical guides withhydraulicintracrestalapproachsinuslift. This technique is a combination of creative thinking from the authors and innovative in- strumentation developed by Hiossen Implant Systems. Four patients were treated using this tech- nique; 20 taper-hydrophilic implants (Hios- sen ET-III) were inserted and integrated over a period of six months.
