Split Crest: The Advanced Technique for Thin Crest Treatment in Implantology
The Split Crest technique is establishing itself as one of the most effective and least invasive solutions for treating cases of reduced bone thickness in the alveolar ridge, a condition that can complicate the insertion of dental implants. Thanks to its ability to expand the available bone thickness without compromising the integrity of the crest, Split Crest offers a highly valid and predictable surgical option.
What is the Split Crest and What is it for?
Split Crest, also known as Split Ridge, is a surgical procedure used in implantology to address the problem of a too-thin alveolar ridge. The technique involves creating a thin groove along the bone ridge using specialized tools such as osteotomes. This groove allows the two bone laminae to be gently separated, creating two distinct septa that provide greater thickness for the placement of dental implants.
Biomechanical Benefits and Healing Time
One of the main advantages of Split Crest is the possibility of using implants with a larger diameter, which guarantee greater primary stability. Numerous clinical studies have shown that this technique significantly reduces healing times, thanks to the reduced initial mobility of the implants. Furthermore, the technique has also proved particularly effective in more complex anatomical areas, with an increase in long-term success rates.
Split Crest Surgical Procedure
The Split Crest procedure is divided into several operational steps. After incision and elevation of the mucoperiosteal flap, a full-thickness central osteotomy is performed in the bony ridge. Using a diamond tip, a groove is created to guide the insertion of the 1-mm osteotomes. These instruments, rotated slowly, complete the separation of the bony ridge into two symmetrical septa, widening the separation groove without causing significant trauma or bone loss.
Post-Operative Management and Follow-Up
Postoperative management is crucial to the success of Split Crest. In the first few days, it is essential to apply antibiotic and anti-inflammatory medications, as well as the use of chlorhexidine mouthwash for two weeks. It is advisable to avoid smoking and physical efforts for about 20 days, and to use an ultra-soft toothbrush for oral hygiene.
After 30-45 days, follow-up radiographs allow evaluation of the bone regeneration process. Immediate loading of implants can be scheduled after 2-3 months, guaranteeing an optimal long-term esthetic and functional result.
Final Considerations
Split Crest is an innovative and rapidly spreading technique that is revolutionizing the field of implantology due to its proven clinical benefits. More and more dental centers are training their specialists on this procedure, which is recognized as one of the best solutions for dealing with reduced bone availability in the alveolar ridge.
