Replacing Multiple Missing Teeth With Implants

Dr. Igor Kaplansky, DDS · April 18, 2026 · 5 min read

Medically reviewed by Dr. Igor Kaplansky, DDS — April 18, 2026

Missing multiple teeth creates a different clinical picture than replacing a single tooth. The right implant solution depends on how many teeth are missing, where they are, how much jawbone remains, and whether the gaps are in one area or spread across both arches. Each scenario has a specific implant-based answer — and all of them outperform removable dentures for long-term bone health and function.

When You’re Missing Several Adjacent Teeth

If you’ve lost two, three, or four teeth in a row, an implant-supported bridge is often the best solution. Rather than placing an implant for every missing tooth, two implants anchor a multi-tooth bridge that fills the gap.

This approach uses fewer implants than individual replacements while still providing a fixed, non-removable result. The implants stimulate the jawbone beneath the bridge, preventing the bone loss that removable partial dentures accelerate.

The alternative — a traditional removable partial denture — clasps onto adjacent teeth and rests on the gum tissue. It doesn’t stimulate bone and tends to shift during eating and speaking. Over years, the adjacent teeth used as clasps can experience increased stress.

When Most or All Teeth Are Missing in One Arch

Full-arch tooth loss requires a different scale of solution. The most commonly discussed option is All-on-4, which uses four strategically angled implants to support a complete fixed arch. Two anterior implants are placed vertically; two posterior implants are tilted at 30–45 degrees to maximize contact with denser bone and avoid the sinus cavity, often eliminating the need for bone grafting.

The TeethNow system at this practice takes a similar approach but uses six to eight zirconia implants per arch rather than four titanium ones. The additional implants distribute load more evenly and the zirconia prosthesis offers superior long-term aesthetics.

Both approaches deliver provisional teeth within 24 hours of surgery. Permanent restorations follow after osseointegration is complete — typically three to five months.

Full-arch cost ranges in Western New York:

  • All-on-4: $20,000–$30,000 per arch
  • TeethNow-style zirconia full arch: $30,000–$45,000 per arch
  • Implant-supported dentures: $15,000–$35,000 per arch

When Bone Loss Complicates the Picture

Prolonged tooth loss accelerates jawbone resorption. Patients who’ve worn full dentures for years often find they’ve lost significant ridge volume — sometimes enough to make standard implant placement difficult.

Options in this situation include:

Bone grafting: Rebuilds the ridge over three to nine months, then allows standard implant placement. Appropriate for moderate bone loss.

Zygomatic implants: For patients with severe upper jaw bone loss, zygomatic implants anchor into the cheekbone rather than the jaw ridge, bypassing the need for grafting entirely. Dr. Igor Kaplansky, DDS — Diplomate ABOI/ID, Fellow AAID/FICOI/FAGD, ZAGA Center certified — is one of only 11 ZAGA-certified zygomatic implant specialists in the United States. The full explanation of zygomatic implants covers who qualifies and what the procedure involves.

Choosing the Right Solution for Your Situation

No single formula applies. A patient missing six non-adjacent teeth has a different treatment plan than a patient missing six consecutive teeth in the upper arch. Key variables include:

  • Location and distribution of missing teeth
  • Bone volume at each site
  • Whether any teeth will be extracted as part of treatment
  • Budget and timeline preferences

The starting point is a 3D CBCT scan and clinical evaluation. At Dentistry by Dr. Kaplansky in Gasport, NY, consultations are offered at no charge. Patients from Lockport, Niagara Falls, Buffalo, and across Western New York are welcome to schedule an evaluation and receive a specific treatment plan.
