Introducing new Wide Ponto Implant and 12 mm Ponto abutment
Oticon Medical recently unveiled innovative new technologies and a broader range of options within the Ponto System, designed to improve implant loading conditions and support the development of new surgical techniques with the potential to improve the cosmetic outcome for patients. A new wide Ponto implant features OptiGrip, a ground-breaking implant geometry that maximizes implant surface area in contact with the bone, an established method to improve implant stability(1)(2). The new and longer 12 mm Ponto abutment is unique to Oticon Medical and gives surgeons increased flexibility to adapt to individual variations in skin thickness.
Designed for improved stability
The new Wide Ponto implant combines a wider implant diameter (∅ 4.5 mm) with the new OptiGrip implant geometry to provide the largest initial bone contact surface in the industry. The resulting improvement in initial stability compared to the ∅ 3.75 mm Ponto implant has been confirmed in preclinical tests in artificial bone material. Studies investigating the clinical benefits are ongoing.
Maximized surface area and improved cutting performance
10% larger initial implant surface in contact with bone
The OptiGrip geometry increases the initial implant surface in contact with bone by 10% compared to any other bone anchored hearing implant. This is achieved though a maximized implant surface combined with unique cutting properties that minimize the required drill hole. This enables the threads to engage deeper in the bone.
27% less bone removal
Due to the smaller drill hole, the OptiGrip implant geometry reduces bone removal by 27% compared to other bone anchored hearing implants of the same diameter. This minimizes intervention and aims to reduce the risk of overheating.
New possibilities for monitoring stability
The new Ponto connection screw is compatible with the Osstell® ISQ instrument for Resonance Frequency Analysis (RFA) using the Implant Stability Quotient (ISQ).
One universal interface
To simplify the monitoring of different implant and abutment interfaces, we adhere to the Ponto principle of a single, universal interface. This guarantees full backwards compatibility, and no alterations to either the surgical procedure or reusable instruments for the new wide Ponto implant.
To make Ponto implants and interfaces simpler to identify – and to make it easy to establish which sound processor alter-natives can be offered to patients – the Ponto connection screw has been colored green.
Adaptable solutions to meet different needs
A skin-friendly design concept
The Ponto design concept is based on three principles aimed at preventing skin irritation and infection.
- Adaptability to different patient needs and surgical techniques
- Minimal movement of skin against the abutment
- Minimum pockets and pathways for bacterial growth and migration
One size does not fit all
The wide range of Ponto abutments offers the flexibility to adapt to different skin thicknesses by matching the distance between the implant flange and abutment shoulder. The Ponto System features three abutment lengths – 6 mm, 9 mm, and new 12 mm – and an angled abutment to correct sound processor orientation for acoustic, practical or aesthetic reasons. All of the abutments are compatible with the new wide Ponto implant.
New 12 mm Ponto abutment
The new and longer 12 mm Ponto abutment is unique to Oticon Medical and intended for patients with thick skin. The range of abutments gives surgeons flexibility to choose an abutment length, adapted to individual variations in skin thickness as well as different surgical techniques. For example, the longer 12 mm length may prove useful in the clinical evaluation of new surgical techniques without soft tissue reduction.
