Summary

The purpose of this study is to present a guided lateral window sinus lift (GLSL) procedure with the aid of a fully digital workflow using surgical templates for window osteotomy preparation and implant placement.

Conditions

  • Lateral Sinus Lifting
  • Dental Implant

Interventions

PROCEDURE

Lateral Maxillary Sinus Floor Elevation using surgical guide

The surgical procedure begins with securing a prefabricated guide firmly to the surgical site. Implant positions are marked, and after guide removal, a crestal incision is made 1 mm palatal to the marked point, extending with sulcular and vertical incisions. A full-thickness mucoperiosteal flap is reflected to expose the maxillary sinus and alveolar crest. After readapting the surgical guide to the bone, implant positions are marked, and cutting edges are tracked. The lateral window is formed by extending and connecting mesial and distal borders, created using piezotome. The sinus membrane is carefully reflected and elevated with a surgical curette to avoid iatrogenic perforation. Implant fixtures are then placed using the identical surgical guide, followed by graft material placement beneath the elevated sinus membrane. If the bony plate is preserved, the lateral window is covered with the plate.

PROCEDURE

Lateral Maxillary Sinus Floor Elevation without surgical guide

The sinus's lateral wall is exposed through a crestal incision and a mucoperiosteal flap. A bony window is created, and upon its removability, the sinus floor is carefully elevated using sinus elevation curettes, taking care to avoid membrane perforation. In cases of perforation, a resorbable collagen membrane is applied to cover the hole. Implant osteotomies are then completed following the standard sequential placement protocol. Graft material, mixed with normal saline, is gently packed into the sinus to fill the cavity with bone substitute material and achieve the desired bone height. Finally, a resorbable membrane is placed on the outer surface of the window, and the flap is sutured for primary closure.
