Some dental implant cases are straightforward. Others require rebuilding the jaw itself before a single implant can be placed. This is one of those cases.
Case #10 at La Mesa Dental Center documents a 5 mm horizontal bone augmentation performed by Dr. Cvetan Mechev, DDS — using 100% autogenous bone harvested from the patient’s own body. The result: a jaw ridge rebuilt wide enough to support a stable, long-lasting dental implant.
The Problem: A Ridge Too Narrow for an Implant
A dental implant is a titanium post that functions as an artificial tooth root. For it to integrate properly, it needs to be fully encased in bone — on all sides.
When the jaw ridge is too narrow, the implant body extends beyond the bone margin, leaving it exposed. That leads to bacterial infiltration, bone loss around the implant, and eventual failure. No amount of surgical skill can compensate for insufficient bone width.
This patient presented with exactly that situation. CBCT imaging revealed a jaw ridge measuring only 2–3 mm at the implant site — far below the 7 mm minimum needed for a standard implant. Without augmentation, implant placement was not possible.
With horizontal bone augmentation, it became possible.
What the CBCT Scans Show
The case imaging tells the story clearly across four cross-sectional views:
- 2 mm — the initial bone width at the narrowest measurement point (red marker), confirming critical deficiency in the second lower premolar area
- 3 mm — an adjacent cross-section, also below the implant threshold in first lower molar area
- 7 mm — the post-augmentation measurement confirming the rebuilt ridge width in second lower premolar area
- 8 mm — the post-augmentation measurement confirming the rebuilt ridge width in the first lower molar area
The 3D CBCT panoramic view shows both the recipient site — the deficient ridge area in the lower jaw receiving the graft — and the donor site — where autogenous bone was harvested from the patient’s own jaw. Both are visible in the intraoral scan overlay.
This is precision-mapped bone reconstruction, not estimation.
Why 100% Autogenous Bone
There are several types of bone graft material available in implant dentistry: synthetic substitutes, donor allografts, animal-derived xenografts, and autogenous bone. Each has its place.
For cases demanding significant ridge augmentation, autogenous bone remains the gold standard. It is the only graft material that is truly osteogenic — meaning it carries living bone-forming cells that actively generate new bone at the recipient site. It doesn’t just provide a scaffold; it builds.
In this case, Dr. Mechev harvested bone from a donor site within the patient’s own jaw, then shaped and secured it at the deficient ridge. The graft was stabilized using fixation screws visible in the panoramic scan overlay, allowing undisturbed healing and full bone integration before implant placement.
No synthetic material. No donor tissue. The patient’s own biology does the rebuilding.
Horizontal vs. Vertical Bone Augmentation
Patients sometimes hear the terms interchangeably, but they address different dimensions of bone loss:
Horizontal augmentation rebuilds the width of the jaw ridge — the buccolingual dimension that determines whether an implant can be fully encased in bone from front to back.
Vertical augmentation rebuilds the height of the ridge — the apicocoronal dimension that determines how deep an implant can be seated.
Some patients need one. Some need both. In the Case #10 that Dr Mechev is presenting the deficit was primarily horizontal — a ridge too narrow to accommodate an implant without lateral exposure. The 5 mm of width gained through augmentation brought the lower jaw ridge from deficient to implant-ready.
For comparison, see Case #9 — a 6 mm vertical augmentation performed using the Safecut technique at the same practice.
Who Needs Horizontal Bone Augmentation?
Horizontal ridge deficiency is more common than most patients realize. Bone resorption begins almost immediately after a tooth is lost, and without a root structure to stimulate the jaw, the ridge narrows progressively over months and years.
You may be a candidate if:
- A dentist told you the ridge is “too thin” for an implant
- You lost a tooth several years ago and the site has not been maintained
- Previous trauma or infection caused localized bone loss
- A CBCT scan shows a ridge width below 6 mm at the planned implant site
Many patients referred elsewhere as “not candidates” for implants are successfully treated with pre-implant bone augmentation.
Dr. Mechev’s Approach: Computer-Guided, Evidence-Documented
Every augmentation case at La Mesa Dental Center begins with a Cone Beam CT scan — a full 3D map of the patient’s jaw that reveals exact bone dimensions at every point along the ridge. This eliminates guesswork and allows Dr. Mechev to plan the graft volume, donor harvest site, and fixation approach before the patient enters the surgical chair.
Case #10 is the tenth in Dr. Mechev’s documented augmentation series — each case tracked with pre- and post-operative imaging, precise measurements, and consistent technique.
Dr. Cvetan Mechev, DDS brings 26 years of clinical experience to every surgical case, with advanced bone grafting training pursued internationally in Dubai( UAE), London(UK), Padua( Italy) and Budapest( Hungary). He performs the full scope of ridge augmentation procedures for dental implants in-office at La Mesa Dental Center:
- Horizontal bone ridge augmentation
- Vertical bone ridge augmentation
- Bone graft for dental implants
- Guided tissue and bone regeneration
- Sinus lift for dental implants

Frequently Asked Questions
How much bone width is needed for a dental implant? Most standard implants require a minimum of 7 mm of bone width for full encasement. At 2–3 mm, the patient in this case was well below that threshold — making augmentation essential before implant placement.
How long does horizontal bone augmentation take to heal? Typically 4 months of healing is required before the augmented site is ready for implant placement. Healing time varies based on graft volume and individual biology.
Is autogenous bone better than synthetic graft material? For large-volume augmentations, autogenous bone offers the highest success rates because it contains the patient’s own living bone cells. Synthetic materials can be appropriate in smaller defects but lack the osteogenic properties of autogenous grafts.
Will I need a second surgical site for bone harvesting? Yes. Autogenous bone requires a donor site — typically within the same jaw, often from the area behind the lower molars. Dr. Mechev plans both sites using CBCT imaging to minimize donor site morbidity.
Does La Mesa Dental Center perform the full implant procedure in-house? Yes. From CBCT scanning and bone augmentation through implant placement and final crown delivery, the entire process is managed at La Mesa Dental Center.
