Bone Ridge Measuring Compass - Helmut Zepf (31.691.13) - Delynov

What is the Helmut Zepf bone ridge measurement caliper?

The bone ridge measurement caliper, referenced under code 31.691.13 by Helmut Zepf, is a manual instrument designed for oral surgery. Manufactured from medical stainless steel, this robust tool allows for direct reading of the bone width. Its structure is specifically designed to be inserted into the oral cavity to evaluate bone dimensions before or during a surgical intervention. As a bone thickness gauge, it offers a reliable solution for practitioners requiring precise morphological data on the recipient site.

What are the clinical indications for the dental bone gauge?

This dental bone gauge is indicated for the quantitative evaluation of the alveolar ridge. In implantology, it is used to measure the residual thickness of the bone to select the appropriate implant diameter or to decide on the necessity of a bone graft (GBR). It is also used in periodontal surgery or during ridge regularization procedures. The use of this bone ridge caliper helps secure the surgical procedure by validating the presence of sufficient bone volume to ensure primary stability of the implant and respect for adjacent anatomical structures.

What are the technical characteristics of instrument 31.691.13?

The Helmut Zepf 31.691.13 caliper is a non-sterile instrument made of high-quality medical stainless steel. Its mechanical design allows for precise handling for measuring ridge thickness. This bone ridge gauge does not have a defined maximum limit of processing cycles, as its durability depends on maintenance and the absence of visible damage such as cracks or breaks. It is imperative to check the condition of the edges and the mechanism before each use to ensure an exact measurement. This device belongs to Class I of medical devices.

What are the contraindications for the use of this thickness caliper?

The main contraindication related to the use of this Helmut Zepf instrument is known hypersensitivity or intolerance to metals, particularly medical stainless steel. If a hypersensitivity reaction is triggered in the patient upon contact, the procedure must be immediately stopped and necessary medical measures must be taken. Additionally, the use of the instrument is contraindicated if it shows visible damage, such as cracks, defects on the cutting edges, or signs of excessive wear, as this could compromise patient safety or measurement accuracy.

What are the maintenance and sterilization precautions?

All Helmut Zepf Medizintechnik GmbH instruments are delivered non-sterile. Before the first use and after each subsequent use, the caliper must be fully cleaned, disinfected, and sterilized. It is crucial to perform thorough cleaning to remove any residue before the sterilization cycle. The practitioner must inspect the instrument for any wear or corrosion. Due to the materials used, there is no predefined limit for reprocessing cycles, but the instrument must be discarded as soon as structural defects appear. This device is exclusively reserved for trained healthcare professionals.

Who is the manufacturer and what standards are met?

The official manufacturer of this device is the company Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This caliper is a manual dental instrument classified as a Class I medical device (Class Ir according to certain reprocessing nomenclatures). The manufacturer imposes strict cleaning and sterilization protocols in accordance with regulatory requirements for reusable devices. Compliance with the safety and maintenance instructions specified by Helmut Zepf guarantees the product's conformity for professional clinical use in dental and implant surgery.
