Crestal Ridge Split & Expansion Kit

ESSET Kit

5 Reasons for choosing the ESSET Kit

In comparison to conventional ridge-splitting techniques involving mallets and chisels—which may cause patient discomfort—the Osstem ESSET Kit provides a gentler, more controlled method for crestal ridge expansion. Its self-tapping expansion drill gradually widens narrow ridges while preserving cortical integrity and leveraging bone elasticity to maximize initial stability.

Why It Matters for Clinicians

Narrow ridge conditions can limit implant placement options and often involve invasive techniques that discomfort patients. The Osstem ESSET Kit offers a minimally invasive, efficient solution—enhancing primary stability while preserving tissue integrity and accelerating healing. This elevates clinician confidence and expands treatment possibilities in anatomically restrictive scenarios, resulting in improved patient outcomes and workflow efficiency.

Key benefits

  • Safe Ridge Expansion
    The expansion drill gently splits and widens the ridge in a self-tapping motion, minimizing the risk of buccal plate fracture while avoiding the need for chisels and malleting.
  • Strong Initial Stability
    By harnessing the expanded bone’s elastic properties, the technique achieves solid primary stability—helping secure implant placement within narrow ridge sites.
  • Reduced Healing Time
    Creation of a 4-wall defect enhances blood supply to the surgical site, promoting faster healing and potentially eliminating the need for additional grafting or membranes.
  • Placing Ø4.0–4.5 Implants in Narrow Ridges
    Enables safe implant placement in cases previously deemed too narrow for conventional approaches, expanding clinical options for clinicians.
  • Minimized Patient Discomfort
    Eliminating the use of mallets translates to a less invasive, more patient-friendly experience.

Safer and predictable expansion of the narrow ridge to secure sufficient room for implant placement

  • The expansion Drill expands the split bone by self-tapping and lowers the risk of bone fracture
  • Achieves strong initial stability by using the elasticity of the expanded bone

ESSET Kit: Expansion Drill

Safer and predictable expansion of the narrow ridge to secure sufficient room for implant placement

  • TThe expansion drill is designed to gradually widen the split bone through self-tapping, thereby minimizing the likelihood of bone fracture
  • Attains initial stability through harnessing the elasticity of the expanded bone

Place implants without excess torque

  • The expansion drill enables implant placement without the need for excessive torque due to the secure expansion and fixation of the split bone

Crest Remover

  • The crest remover facilitates the generation of sufficient bone width necessary for surgery
  • Flattens uneven ridge for implant preparation

Facilitates blood supply and shortens healing time

  • The ESSET technique, through the utilization of a 4-wall defect, facilitates improved blood flow to all sides of the implant, leading to a reduction in healing time

Using the ESSET Kit in action

  • The round-shaped cutting edge drill design minimizes the risk of sinus membrane perforation.
Step 1: Crest Remover - Contour ridge and create grooves for implant sites
Step 2: Initial drilling with twist drill to define implant positioning
Step 3: Saw to incise and split ridge
Step 4: Expansion drill to expand ridge
Step 5: Implant placement into expanded ridge
Step 6: Complete placement
Step 7: Insert the healing abutment
Step 8: Suture and complete the procedure

Study-supported ridge expansion

A controlled clinical study found that split crest procedures using the Osstem ESSET Kit achieved significant bone gain, high implant stability, no reported complications, and 100% implant survival after one year — even in the group treated without grafting. The study is highlighting the potential of the ESSET Kit for efficient, graftless ridge expansion in selected cases.

Evidence-Based Ridge Expansion with the ESSET Kit

Predictable Ridge Expansion — With or Without Bone Grafting

A controlled clinical study evaluated the split crest technique using the Osstem ESSET Kit and TSIII implants in narrow alveolar ridges. The study compared split crest procedures performed without grafting, with alloplastic bone grafting, and with dentin grafting.

 

Key Findings: Across all groups, the split crest approach achieved significant horizontal bone gain, high implant stability, and 100% implant survival after one year. No intraoperative or postoperative complications were reported in the study.

 

Graftless Clinical Performance: Notably, the split crest group without grafting showed excellent results, with an average bone width gain of 2.46 mm after three months and stable ISQ values above the clinical threshold used in the study.

 

Clinical Value: The findings support the ESSET Kit as a reliable solution for horizontal ridge expansion in carefully selected narrow ridge cases. By enabling simultaneous implant placement, the technique may help reduce treatment complexity, surgical steps, and the need for additional grafting procedures.

 

Evidence Note: This was a preliminary controlled clinical study involving 24 Osstem TSIII implants placed in 12 patients. The authors concluded that split crest with simultaneous implantation was successful and predictable in narrow ridges with sufficient bone height, both with and without bone substitute material.
