When several teeth are missing — whether in the front of the mouth, the back, or across both jaws — the impact goes well beyond aesthetics. Chewing becomes uneven. Remaining teeth begin to drift. Bone resorption accelerates in the gaps. The longer multiple teeth stay unreplaced, the more complex and costly the eventual treatment becomes.
Dental implants remain the most anatomically correct solution for multiple tooth loss. Each implant replaces a root, maintains bone volume, and supports a crown or bridge that functions like natural dentition. At our Beirut clinic, multi-implant cases are designed and placed by Dr. Habib Zarifeh — Head of Oral Surgery at CMC Hospital Beirut (Johns Hopkins International affiliated), holder of an MSc in Laser Dentistry from RWTH Aachen University, Germany, and founder of Smile Infinity® across 12 countries.
Not every missing tooth requires its own implant. When multiple adjacent teeth are absent, Dr. Zarifeh and his prosthodontic team evaluate whether individual implants per tooth or a shared implant-supported bridge delivers the best long-term outcome for that patient.
For example, four adjacent missing teeth can often be restored with three implants supporting a four-unit bridge — or in carefully selected cases, two implants with a four-element bridge. This approach is considered when patient anatomy, bone availability, or medical factors make it the most appropriate plan. Every recommendation is evidence-based and tailored to the individual case — never driven by cost shortcuts.
Using Dr. Zarifeh's One Day Implant® protocol, multiple implants, abutments, and a definitive zirconia bridge can all be completed in a single surgical session. The procedure uses laser-assisted flapless surgery — no incisions, no sutures — combined with Sirona MCXL inLab CAD/CAM technology to mill a precision zirconia bridge chairside on the same day.
This protocol requires ideal bone quality and quantity. It is most predictably performed in the lower jaw. When conditions are right, patients leave the clinic with a fixed, permanent multi-tooth restoration the same morning they arrived.
Where immediate permanent loading is not indicated — particularly in the upper jaw or aesthetic zone — immediate temporization provides a fixed temporary resin bridge on the day of surgery. The patient is never without teeth.
This technique serves a clinical purpose beyond comfort: it shapes the gum tissue around each implant during the healing phase, producing better soft tissue architecture and a more natural final result. The temporary bridge is produced either chairside with CAD/CAM or through conventional laboratory methods. Both upper and lower jaw cases qualify for this approach.
For patients requiring bone grafting, presenting with compromised bone density, or with medical considerations that demand extended healing time, the conventional protocol delivers the most predictable outcome. Implants are placed with healing or cover screws in the first session. The definitive bridge is fabricated and fitted after full osseointegration — typically over several weeks to a few months, depending on the number of implants and individual healing response.
This staged approach allows Dr. Zarifeh to monitor each implant's integration individually before loading the final restoration — the right choice when precision matters more than speed.
