Ridge Splitting Procedures

There are situations where patients require implant in which there is sufficient bone length but there wont be sufficient width. If there is a problem with bone height, we can do bone augmentation or sinus lift. But what about the insufficient width That is where the ridge split option exist.

Ridge widening or augmentation is achieved by splitting the crest of atrophic and edentulous bony ridges. When ridges are narrow at about less than 4mm in width, they might require horizontal augmentation to place dental implants. A lateral ridge split technique usually resolves the problem of narrow ridges allowing simultaneous placements of dental implants.

The ridge split technique is either a one stage procedure where implant is placed simultaneously or as 2 stage procedure in which first ridge split and bone augmentation and later date implant placement done.
Dr. Sudhakar Reddy performs the ridge split technique to widen the narrow ridges and achieve adequate height for implant insertion.

  • The simultaneous placement of the implants reduces healing times.
  • The survival rate of these implants is more than 98% with autogenous bone or biomaterials used for grafting.
  • Acceptance rates of patients are extremely high with this technique.
  • It is a minimally invasive technique with high advantages during the preprosthetic stages of a dental implant
  • The technique is low risk causing minimal inferior alveolar nerve injuries

Surgical procedure

  • Local anaesthesia is administered
  • The full thickness of the muco-periosteal and the flap is reflected
  • The crest is prepared with a surgical fissure bur
  • A 8 mm Obwegeser osteome is applied to expand and split the ridge
  • A paralleling device is inserted after adequate width is obtained
  • The prepared site is inserted with implants that have similar diameter since unequal diameters may lead to loosening of small fixture
  • Biomaterial is filled in between the cortical plates
  • The cover screw is tightened
  • Soft tissue closure is achieved
