Indications for Use
BioHorizons Implant Site Dilators are indicated for use to aid in the placement of root form implants in soft maxillary bone. Rather than removing valuable bone from the surgical site, the function of these instruments is to manually form the osteotomy by compressing the bone laterally, causing a denser bone to implant interface.
Device Story
Implant Site Dilators are hand-operated surgical instruments used by oral and maxillofacial surgeons or implantologists. The device functions by manually compressing soft maxillary bone laterally to form an osteotomy for root form implant placement; this process preserves bone at the surgical site and creates a denser bone-to-implant interface compared to bone removal techniques. The device is used in a clinical setting during dental implant surgery. It provides a mechanical aid to the surgeon, directly influencing the surgical technique and the resulting bone density at the implant site, potentially improving implant stability.
Clinical Evidence
Bench testing only; evaluated by consulting implantologists and oral and maxillofacial surgeons.
Technological Characteristics
Hand-operated surgical instruments; material: surgical grade stainless steel; form factor: manual dilators; no energy source; non-software; non-electronic.
Indications for Use
Indicated for use in patients requiring root form dental implants in soft maxillary bone to aid in osteotomy formation via lateral bone compression.
Regulatory Classification
Identification
An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.
Special Controls
*Classification.* (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2) *Classification.* Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use; (ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads; (iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system; (iv) The device must be demonstrated to be biocompatible; (v) Sterility testing must demonstrate the sterility of the device; (vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment; (vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians; (viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and (ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.
