The best alternative to sinus lifting

At Lux Dental Clinic in Vilnius, modern implant protocols are applied that allow avoidance of sinus lift by positioning implants in naturally dense and stable anatomical areas of the patient’s bone, subject to individual clinical assessment.

This approach includes:

• cone beam CT (CBCT) analysis for treatment planning and implant positioning;
• implant systems designed to achieve fixation in specific anatomical zones;
• fully digital 3D planning of the surgical and prosthetic stages;
• calculation of implant angulation and depth based on full-arch biomechanics;
• customised 3D-printed surgical guides;
• multi-unit abutment systems that allow immediate provisional restoration;
• the use of established implant systems such as Straumann and JDental.

• Angled posterior implants are used to redistribute occlusal forces while avoiding the maxillary sinus;
• Trans-sinus implant positioning may allow anchorage in stable basal bone without elevation of the sinus membrane;
• In cases of advanced bone resorption, nasal or zygomatic implants may be considered, engaging anatomically strong bone structures.

Where clinically indicated, this approach allows provisional fixed teeth to be placed on the day of surgery, maintaining function, speech, and soft-tissue support during healing.

• A single surgical procedure;
• avoidance of surgical intervention in the maxillary sinus;
• placement of provisional fixed teeth on the day of surgery;
• reduced overall treatment time;
• lower surgical burden;
• high primary implant stability;
• predictable long-term functional outcomes.

Implants anchored in the patient’s own dense bone demonstrate favourable conditions for osseointegration and long-term stability.

Digital planning enables optimal use of the patient’s individual anatomy without routine involvement of the maxillary sinus.

Implants placed in dense and stable bone:

• provide high primary stability;
• are suitable for immediate loading protocols;
• demonstrate reduced susceptibility to long-term remodelling;
• form a reliable foundation for fixed full-arch prostheses.

In full-arch treatment concepts such as All-on-4 or All-on-6, implants are connected by a rigid prosthetic framework and function as a unified biomechanical system.

Key considerations include:

• distribution of occlusal forces across multiple implants;
• the importance of primary stability rather than local bone volume;
• the use of angled and deeper implants in dense bone to support effective load transfer.

Sinus lift is associated with:

• increased surgical complexity;
• potential risk of sinus membrane perforation and postoperative sinus complications;
• extended treatment timelines;
• delayed application of immediate loading protocols;
• no demonstrated improvement in long-term stability of full-arch restorations.

In patients with sinus pathology, advanced maxillary atrophy, or age-related changes of the sinus mucosa, sinus lift may be contraindicated.

Bone graft material:

• does not possess the same density as native basal bone;
• may undergo remodelling and resorption over time;
• is less suitable for immediate functional loading.

In full-arch rehabilitation, reliance on grafted bone may reduce predictability compared with treatment approaches based on stable anatomical bone structures.

• Clinicians with extensive experience in full-arch implant rehabilitation;
• Individualised digital 3D planning for each patient;
• High precision in implant placement;
• In-house design of surgical guides;
• Coordinated care for international patients;
• A high volume of full-arch treatments performed annually;
• Contemporary implant protocols that prioritise stable anatomical bone and may eliminate the need for sinus lift, depending on clinical indications.
