Designed for both transitional and long-term denture stabilization, the ERA Micr
Designed for both transitional and long-term denture stabilization, the ERA Micro Dental Implant features the capability to correct implant mis-angulation. Four unique angle options offer flexibility to achieve the desired path of insertion for denture stabilization, even when implants are placed in narrow, resorbed ridges. The ERA implant enables the transitional function of a denture during the osseointegration of traditional implants, as well as long term, affordable chairside denture stabilization. This multi-dimensional system comprises the ERA implant, prosthetic components, including the angulation-correction, vertically resilient properties of the ERA Attachments. For surgical implantation in the maxillary or mandibular arch to support dental restorations such as artificial teeth, in order to restore the patient’s chewing function. Intended for long-term as well as temporary surgical implantation in the bone of the patient’s upper or lower arch to provide immediate load or delayed load of prosthetic systems. Immediate loading should only occur when the position of the implants provides adequate bone quantity and quality to allow proper immediate mechanical stabilization of the self-tapping screw into the bone.

A metal device used in dental surgery to create channels of appropriate depth and diameter in bone (osteotomy) of the oral cavity to facilitate the implantation of a dental fixture/appliance. There are depth marks along the length of some drills corresponding to the different size implant bodies. These marks are laser etched. Some drills are marked with the diameter in millimeters on the shank. Intended to be used to generate the bore into the bone into which an implant body or attachment is installed into.

Preparation of the bony receptor site involves the sequential use of drills and drilling components. Sterngold Implamed offers two drilling configurations; Externally Cooled Twist Drills and Internally Cooled Spade Drills. Both styles are precision machined from high strength stainless steel and feature convenient depth markings and standard latch-type connectors.

Devices are used in dental implant applications for oral rehabilitation of edentulous and partially dentate patients in the maxilla and mandible. Implant retained restorations may consist of single crowns or bridges as well as complete or partial dentures. Healing Abutments are intended for placement onto the implant during stage II surgery. As the tissue heals, it conforms to the contours of the abutment. As the gingiva heals, the tissue adapts to the form of the healing abutment, creating permanent oral access to the implant and prepares the gingiva for restoration.
