Conodent Osteotome Concave Straight Set (Model: CDT-F-254)

Premium 5-Piece Concave Bone Condensing & Sinus Floor Elevation System

Product Overview

The Conodent Osteotome Concave Straight Set (Model: CDT-F-254) is a highly specialized dental implantology kit containing 5 progressively sized instruments engineered for closed sinus floor elevations (Summers Technique), bone condensing, and apical grafting procedures. Featuring a cupped, concave tip profile integrated onto a rigid, straight shaft body, this set is designed for efficient, direct linear force distribution primarily within the high-visibility anterior and premolar regions of the maxilla.

During internal sinus lift protocols, safely elevating the sinus floor requires meticulous hydraulic or mechanical control to prevent tearing the delicate Schneiderian membrane. The CDT-F-254 series utilizes a concave tip pocket that securely traps bone graft matrix or autogenous bone slurry. As the instrument is advanced, it drives the graft material directly ahead of it, using the bone mix as an cushion to lift the sinus floor safely and smoothly.

Kit Configuration & Sequential Sizing

The 5-piece configuration scales across standard progressive tip diameters to facilitate a safe, stepwise site widening and elevation workflow:

• 2.6 mm Osteotome: 1x Concave Straight — Initial site tracking, pilot site compression, and early grafting stages.

• 3.1 mm Osteotome: 1x Concave Straight — Intermediate site expansion and baseline sinus floor elevation.

• 3.8 mm Osteotome: 1x Concave Straight — Standard platform expansion (optimized for matching ~3.5–4.0 mm implant profiles).

• 4.5 mm Osteotome: 1x Concave Straight — Wide-platform site preparation and high-volume graft condensing.

• 5.0 mm Osteotome: 1x Concave Straight — Large-diameter site scaling for broader restorative platforms.

Core Design Features & Clinical Benefits

• Apical Compacking Concave Tips: The hollowed, cupped design safely captures particulate bone graft material or autogenous bone slurry. As the mallet strikes the instrument, the tip compresses and drives the graft material apically. In internal sinus lifts, this creates a protective cushion of bone that hydraulically lifts the delicate Schneiderian membrane, drastically minimizing perforation risks.

• Straight Shaft Inline Alignment: The completely straight profile provides excellent vector translation and maximum tactile feedback. It allows the surgeon to feel bone density variations directly, ensuring precise axial control in the anterior and premolar regions.

• Calibrated Laser Depth Benchmarks: Features high-visibility laser markings etched at standard implant length benchmarks (8 mm, 10 mm, 13 mm, 15 mm, 17 mm, and 20 mm). This provides real-time depth monitoring during intraosseous advancement without needing separate depth indicators.

• Impact-Resistant Handle & Cap: Built from a unified core of tempered surgical steel to withstand repeated mallet impacts without structural mushrooming, micro-cracking, or hand fatigue.

Primary Clinical Applications

• Closed Sinus Floor Elevation (Summer’s Technique): Safely elevating the sinus floor through the osteotomy site by utilizing bone graft cushion mechanics in the anterior maxilla or premolar region.

• Apical Bone Condensing & Transport: Forcing bone grafting substitutes or autogenous bone slurry vertically into the floor of an osteotomy socket to increase the vertical height of available bone.

• Cancellous Bone Condensation: Compacting loose or soft trabecular matrix bone to dramatically improve the initial primary stability of immediate or delayed dental implants.
