Abstract: Objective To assess the clinical efficacy of a new instrument in lateral window maxillary sinus lifting.Methods 34 patients with 51 posterior teeth lost were augmented with lateral window maxillary sinus lifting,22 patients using Dentium Advanced Sinus Kit as the experiment group and 12 patients using common ball drill as the control group.Then the sinus floor was elevated,filled with artificial bone,and the implant was inserted simultaneously,covered with biological membrane.The time of lateral window,the membrane perforation rate,patients′ subjective feeling during operation and the postoperative reaction three days after operation,as well as the situation of sinus and osseointegration of implant while finishing restoration in two groups were compared.Results ①The time of lateral window in the experiment group((7.34±0.72) minutes) was less than that in the control group ((17.84±1.29) minutes).②The membrane perforation rate of the experiment group was 0,which was less than the control group (16.7%).③The painful and swelling feeling in the experiment group was slighter than that in the control group.4.All cases had no sinusitis and the bone resorption was less than 1mm.Conclusions The application of DSAK in lateral window maxillary sinus lifting could shorten the surgery time obviously with low membrane perforation rate and slighter postoperative reaction.It is safe ,quick and effective.
