Instructions for Placement of Dental Implants Intra-Lock System "Part 1"

Preoperative Treatment Planning:

Proper patient selection is a critical factor for success. A comprehensive patient interview and medical/dental history must be taken. A complete oral examination should then be conducted. Head and
neck examination is followed by a thorough oral examination. The use of magnification is strongly encouraged as an adjunct to all procedures.
Oral inspection includes palpation and the proper radiographic protocol(s). This may include periapicals, panorex and tomograms. Palpation of the ridges is also required and the use of intra-oral probes
for tissue thickness is recommended. The diagnostic procedures will give the dentist an appreciation for
the tissue quality and thickness, ridge morphology for the type and size of the implants that might be required. Measurements for implant size can be estimated utilizing radiographs, templates, calipers and millimeter rulers.
Treatment planning should also take into consideration prosthetic biomechanics, occlusion and occlusal load. Fracture due to excessive load or metal fatigue can occur on the implant body or its prosthetic
components if this aspect of planning is inadequate

Surgical Asepsis:
The operating field must be isolated with sterile coverings as much as possible. As with all surgical procedures, the operatory field should be maintained with sterile coverings (light handles, chair controls,
bracket tray, and all instruments and components). Barrier technology, sterile solutions and sprays, sterile coverings, and proper autoclaving techniques must be employed as indicated

Precautions:
• Sterilization: Dental implants should not be recleaned or sterilized if contaminated. Surface characteristics will be altered and may result in implant failure
.
• Prosthetic components and drills may be autoclaved or cold sterilized via standard procedures.

• Warning: Melting point of outer plastic package is 200°F. Remove prior to autoclaving.

• Handling: The external surface of titanium dental implants should only come in contact with titanium surfaced instruments. All implants are provided suspended on two titanium cradles and are designed for
use with the Drive-Lock® drivers.
• This method will enable proper handling, transport and implantation procedures.
Soft Tissue Site Preparation:
Once prepped (site isolation and local anesthesia achieved), the surgical procedure begins with dentification of the implant site(s) via the creation of bleeding point(s). A mesio-distal incision is then made on the alveolar crest, extending approximately 3-5 mm beyond the implant site(s). It is imperative that a clear visual field be maintained at all times. The incision should penetrate to the full depth of the gingiva and the periosteum. A periosteal elevator is used to lift the periosteum and expose the alveolar bone. Any irregularities or deformities of the alveolar ridge should be eliminated or ameliorated at this time. The istance between implants and/or the natural dentition should be maintained within a range of 4-6 mm.

Penetration of the Alveolar ridge:
Of critical importance is the fact that all bone-cutting procedures are CONDUCTED AT SLOW SPEEDS (60-1200 RPM). Profuse, internal and/or external irrigation is also mandatory.

Drilling Technique:
The slow-speed, highly irrigated drilling procedure is conducted while angling the drill such that the direction of the drill bisects the ridge. The drill should also be held vertically, avoiding a mesial or distal cant. Depth gauge/alignment components can be periodically inserted into the osteotomy site to monitor the angle of penetration. Successively larger drills are used until the desired diameter is achieved. Drilling is performed with a precise, up and down pumping action. The drill angle is maintained in order to preserve the oncentricity of the hole, while the pumping action allows for incremental depth penetration and periodic cleansing of the flutes. A Pilot Hole should be drilled where the bone is of high density. The
“Lancer” Pilot drill is used for this procedure. It is recommended that the pilot hole extends to a depth of 8 mm
