Surgical instrumentation

The unique OptiGripTM geometry of the Ponto implants allows for a drill design that better preserves the bone. The unique tailor-made MIPS surgical components are designed for surgical control and precise tactility. The non-disposable surgical instrumentation can be used both for MIPS surgery and traditional techniques and provides the core instrumentation with everything necessary to successfully perform the surgery.

Ponto surgery

MIPS involves making an incision with a diameter of 5 mm. The tailor-made MIPS Surgery Kit provides everything you need in one blister pack.

 

The MIPS surgery features the Cannula - an instrument that ensures correct drilling and cooling while protecting the soft tissue. This is the key to the minimally invasive approach that provides all the benefits of MIPS.

For an overview of the procedure, please see the Surgical addendum for MIPS and the Surgical manual for tissue preservation surgery with linear incision.

Traditional bone anchored hearing surgery normally involves an incision line of 2 - 4 cm, sometimes together with a  5 mm diameter punched incision. For this procedure a traditional Guide drill and Countersink drill are used.

Disposable instruments

   

MIPS Surgery Kit, 4 mm

The MIPS Surgery Kit, 4 mm is used in the MIPS single-stage procedure for installation of 4 mm wide (Ø4.5 mm) Ponto implants. It consists of Cannula, Cannula Guide Drill, Cannula Widening Drill 4 mm and Soft healing cap.

 

MIPS Back-Up Kit, 3 mm

The MIPS Back-Up Kit, 3 mm is used in the MIPS single-stage procedure for installation of 3 mm wide (Ø4.5 mm) Ponto implants, as back-up in case of insufficient bone depth for the 4 mm implant. The kit consists of Cannula and Cannula Widening Drill, 3 mm.

 
 

Traditional surgery

This is often a linear incision 2-4 cm, with either tissue preservation or reduction. The Guide drill supports a drilling depth of both 3 mm and 4 mm. The Wide countersink, marked with a "W" indicating it is intended for wide (4.5 mm) Ponto implants, comes in two sizes of either 3 or 4 mm.

 
 

Soft healing cap

The resilient design of the Soft healing cap with its open processor interface enables connection of the sound processor while the healing cap is still attached.

Non-disposable instruments

 

Double-ended Dissector

The Double-ended Dissector is used for dissection and removal of the periosteum. The blunt side is also used for inspection of bone.

 

Sterilization cassette

The sterilization cassette presents the sterile instrumentation in a structured way. It is fully compatible with modern hospital infection control systems.

Ruler

A Ponto implant system-specific device for measuring skin thickness with an abutment choice indicator up to 14 mm.

Counter torque wrench

This wrench counteracts the force when tightening the connection screw or mounting the Abutment extension using the screwdriver.

Torque wrench

With a scale of 10-35Ncm, the torque wrench is used with the screwdriver to secure the correct torque when tightening the connection screw or mounting the Abutment extension.

Handle with screwdriver

The handle, with replaceable bits, can be used together with the torque wrench. It is delivered with one screwdriver machine bit.

 

Screwdriver machine bit, 35 mm

This bit can be used with both the screwdriver handle and the drill equipment handpiece. It fits all abutment connection screws, implant adapter screws and the Abutment extension.

Abutment inserter, machine

During the single stage surgical procedure, the abutment inserter is used for inserting the implant with the pre-mounted abutment.

 

Insertion indicator

The insertion indicator is used as a guide to visualize installation of the implant.

 

Square fit connection, machine

The square fit connection is used for inserting the 3 mm or 4 mm implant with the pre-mounted implant adapter in two-stage surgery.

Sound processor indicator

The indicator helps to indicate the correct implant position on the skin when marking for surgery.

 

Screwdriver hexagon

The hexagon screwdriver is used for screwing and unscrewing the cover screw.

Ampoule holder

The stand is designed to hold the sterile component ampoule during surgery.

Drilling equipment

Oticon Medical recommends the Implantmed drilling system with a contra-angle handpiece 20:1 from W&H. Settings and specifications are covered in the Setting Guide.

ISQ. Measuring implant stability

The ISQ (Implant Stability Quotient) measurement scale uses Resonance Frequency Analysis (RFA) to evaluate implant stability. The Osstell ISQ and Osstell Mentor stability meters provided by Osstell can be used to measure the ISQ. The values range from 1-100. The more stable the implant and the harder the bone, the higher the ISQ value. More information can be found in the Osstell ISQ Quick Guide.

Immediately recognizable

The Ponto abutment has a green connection screw which indicates full compatibility with the Osstell ISQ instrument for evaluating implant stability. This measurement only takes a minute to perform.
