Bone preparation operation for implant insertion:

The Short Drills Set is a set of instruments for bone tissue preparation and installation of two-stage dental implants 6.0 mm, 7.0 mm, 8.0 mm, 10 mm long with an internal connection of 2.43 mmd and an implant diameter of 3.0; 3.3; 3.75; 4.2; 5.0mm, which is comparable with other systems with a hexagonal socket H2.43 mm (Zimmer, Green, Direct, MIS, Alpha Bio, Pal top, Bio Horizon, etc.). Preparation of the bed for the bone implant depends on the type and volume of the jaw bone, the method of dental implantation and the type of bone drills. The implant bed is prepared sequentially using drills of increasing diameter with integrated drilling depth stoppers. All bone preparation must be done with copious cooling of the drill and jawbone with sterile and cold saline and using the intermittent drilling technique. Intermittent drilling technique: the drill enters the bone and goes into it by 2-3 mm. Then you make the opposite movement - the drill comes out of the bone. The cut bone comes out of the bone hole together with the drill, it must be removed with suction. Then the process is repeated until the planned drilling depth and diameter is obtained.

Drilling sequence:

Mark the bone with a round bur (173419) to a depth of 2-3 mm. Then prepare the bone with a 2 mm drill (401120). After preparation with a 2 mm drill to a depth of 8 mm, it is necessary to install a titanium depth gauge and, in parallel with it, perform an X-ray examination in the prepared hole - a periapical (aiming) or panoramic image. Titanium depth gauge (451630) and a shortened titanium depth gauge (451030) to determine the depth and parallelism of bone tissue preparation. Considering that the thread pitch on the template is 1 mm, it is possible to determine with high accuracy how far we are from the nerve trunk, tooth, etc., and also to determine how parallel the drilling is compared to the teeth, implants, etc. And only after this is further preparation of the bone bed of the implant carried out. If you need to install several implants. It is recommended to maintain a minimum distance of 3.5 mm from each implant to the next. During the drilling stage, it is necessary to constantly inspect and examine the bone hole or socket of the extracted tooth. For this purpose, an implant bone depth gauge (450001) is used, which is a pen with a two-sided working part. The working part has notches indicating the drilling depth into the implant bone bed. The first notch is 8 mm, then 10 mm, then 11.5 mm, then 13 mm, then 16 mm. At the end of the working part there is a hemisphere. On one side, its diameter is 1.9 mm, on the other - 3.0 mm. Using this depth gauge allows you to simplify the inspection of the walls and bottom of the prepared bone bed of the implant, determine the presence of perforation of the walls and bottom of the bone bed, and determine the integrity of the bone bed. With this depth gauge, you can examine the mucous membrane of the maxillary sinus, measure the height of the alveolar process to the bottom of the maxillary and nasal sinuses on the upper jaw and the mental foramen on the lower jaw, take the necessary measurements during the operation and choose the tactics of further actions. Continue drilling with an increase in the drill diameter. The last drill should be 0.5 mm smaller than the diameter of the implant. Drilling protocols with cylindrical drills are considered classic. This ensures a smoother and easier insertion of the implant into the bone, allowing for complete integration and immersion of the implant into the bone. This also prevents complications such as: - bone overheating, - bone fracture, - fracture of the implant hexagon, - jamming of the implant carrier or implant driver key in the implant hexagon.

Implant is installed:

The implant is installed using a 2.43 mm Allen key (430525, etc.) for implants with an internal hexagon H2.43 (length from 6 mm to 11.5 mm and diameter from 3.75 mm to 5.0 mm) and with an internal cone + hexagon CH2.43 (length 8 mm and 11.5 mm with diameter from 4.2 mm and 5.0 mm) or a 2.1 mm Allen key (430521, etc.) for implants with an internal cone + hexagon CH2.1 (length 8 mm and 11.5 mm with diameter from 3.3 mm and 3.75 mm). The keys have hexagon edges along the entire working part of the key, which help to visually determine the position of the implant hexagon. It is recommended to place the flat part of the key edge on the vestibular side so that standard abutments can be used. In addition, there are two circular marks on the keys indicating the depth of the implant insertion relative to the bone: the gingival mark is at 3 mm, and the second is at 5 mm. After inserting the implant and removing the implant carrier, it is necessary to close the internal connection of the implant. There are several approaches:

1. Two-stage implantation - installation of a screw-cover, which is in the sterile implant kit. Using a 1.27 Allen key (431112, etc.), take a screw from the sterile package and screw the cover into the titanium implant.

2. One-stage implantation.

The titanium healing abutment for implants is installed on the implant immediately after the implant is installed in the bone. Using a 1.27 mm Allen key (431112, etc.), screw the healing abutment into the titanium implant. The height of the abutment is selected based on the thickness of the gingival margin in each clinical case. Recommended: the height of the healing abutment should be at least 1 mm higher than the gingival margin, and the healing abutment should not come into contact with antagonists and adjacent teeth. 

Warnings:

The packaged medical device is not sterile. It is recommended to sterilize in an autoclave at 135 °C / 274 °F before use. The dentist / maxillofacial surgeon should be well acquainted with the technology of using the surgical kit with a stopper. The drills in the kit should be replaced when their cutting efficiency decreases. It is recommended to change the drills after 30-50 drillings. When the cutting efficiency of the bone drill decreases, undesirable complications occur: - large collateral edema of soft tissues; - severe postoperative pain; - an increase in the number of dead bone cells in the prepared bone bed of the implant and, as a result, implant rejection; - drill fracture; - a crack or chip in the jawbone, etc.
