Background: The posterior maxilla is always a challenge for dental implant restoration. The presence of maxillary sinus and reduced subantral bone height are the limitations for implant insertion. The need of the hour is to make the surgical procedures simple, minimally invasive, andpredictable. Can we perform the sinus lift and simultaneous implant insertion by minimally invasive,simple, cost-effective, and less time-consuming technique? With this in consideration, the author carriedout this study for graftless crestal hydraulic sinus lift (CHSL) and simultaneous implant insertion in partially edentulous posterior maxilla for 26 implants. The aim is to evaluate the clinical and radiological success of graftless CHSL with simultaneous implant insertion. Material and Method: The sample size was 17 patients and 26 implants were inserted. The clinical as well as radiological follow-up was done for 1 year. The outcome variables were the gain in bone height and implant survival. Result: Mean Bone height Gain is 5.6 mm; Mean torque used 32 nm, Mean age of the patient was 53 years. The literature shows a success of graftless lateral and osteotome-mediated sinus lift. The concept is the blood filling the gap around the implant in tented sinus lining can eventually result in the ossification to form bone. Until now, no study has demonstrated the bone formation in the peri-implant area of CHSL with simultaneous implant insertion. CHSL, a minimally invasive sinus lift surgery is very encouraging, easy to master, and predictive. The simultaneous implant insertion acts to retain the elevated sinus lining by tenting. It also reduces treatment time. After a sinus lifting procedure, the compartment around the implants under the sinus mucosal lining in the sinus floor is filled with a blood clot from surrounding bleeding. Blood clot can be considered autologous osteogenic graft material, to which osteoprogenitors can migrate, differentiate, and regenerate bone. Conclusion: The graftless CHSL is predictable and safe for the sinus lift. The gain of up to 5–6 mm of subantral bone is possible.
