Summary

This study was carried out to compare the outcome of sinus lift without grafting material, versus the use of moldable, self hardening calcium phosphate biomaterials with simultaneous implant placement.

Detailed description

This study was designed as a randomized controlled clinical trial, the study population consisted of 20 patients with missing maxillary posterior teeth and residual bone height 5-7mm. The sample was selected conveniently according to a list of inclusion and exclusion criteria, the participants were allocated randomly into two equal groups. All patients had sinus lift using piezosurgery device with simultaneous implant placement. In group I, blood clot was the only filling material. In group II, moldable, self-hardening calcium phosphate was the filling material. Clinical and radiographic evaluations were done through 6 months postoperatively.

Conditions

• Maxillary Sinus Augmentation

Interventions

Type	Name	Description
OTHER	Moldable self-hardening biphasic calcium phosphate graft	Incision was performed in the canine area then a full thickness mucoperiosteal flap was elevated and exposure of the lateral aspect of the maxillary sinus. Osteotomy of the buccal window was performed using the piezosurgery device followed by meticulous dissection of the sinus membrane. Drilling the site were implants were to be placed, guided by the preformed surgical stent. Implants of appropriate size were torqued to engage the apical aspect of the implant recipient site. The sinus was augmented with moldable self-hardening biphasic calcium phosphate. Repositioning and suturing of the flap using 3-0 black silk suture material.
PROCEDURE	No graft material placed - Blood Clot only	A pyramidal full thickness mucoperiosteal flap was performed distal to the canine area with a crestal incision located palatally in the edentulous area and vertical extension of the incision to the buccal vestibule using Bard Parker blade number 15. The flap was reflected exposing the alveolar bone. Lateral window was performed and the sinus membrane was elevated using piezo surgery. Drilling at the sites where implants were to be placed was done using Neobiotech implant drilling Kit. Implants. Implants were placed in a self-tapping fashion using a torque wrench. Flaps were replaced back and sutured using 3-0 black silk suture material.
