	The esthetic zone is always a challenge for implant restoration. The problem of losing gingival height following extraction jeopardizes achieving the natural look of the crowns placed on the implants.

Bone defects surrounding the tooth prior to extraction add additional complication to the treatment as, in most cases, the bone will not regenerate following extraction of the tooth and, as a result, there will not be sufficient bone for placing an implant and for achieving the desired esthetic result.

 offers a wide range of implant systems plus compatible implant systems that do not require dental clinicians to invest in additional surgical kits. HI-TEC is in close contact with dentists and is dedicated to addressing their needs in a short period of time.

In fact, the company was founded by dental professionals with clinical experience who look forward to an ever-expanding market as more and more dentists offer implant services. Usage is increasing across all categories of implants, and dentists interested in placing implants should start learning about the variety of options and solutions HI-TEC offers, and solve each case with the implant that is ideal for the situation.

In this particular case, a tapered self thread implant was used in an esthetic zone for an implant restoration in a site with bone defect.

A 42-year-old male patient had his first upper pre-molar tooth extracted due to a vertical fracture of the buccal root. This left a perforation of the buccal plate. 

The treatment chosen for the rehabilitation of the missing tooth was to place a wide platform tapered 4.20mm implant simultaneous with bone augmentation and to construct a porcelain crown using a zirconium abutment for building the porcelain directly bonded to it.  

from HI-TEC Implants was selected as most suitable for achieving initial retention in the bone defect and as the wide platform has the closest fit to the socket.

In order to achieve the ultimate esthetics, the accurate positioning of the implant is essential as well as meticulous soft tissue management.

 The surgery was performed 6 weeks after extraction. 

 shows the site prior to surgery. A full flap was opened, exposing the large crater and the perforation of the buccal plate (

A 2.0mm pilot drill was used to drill beyond the depth of the socket (

) and was followed by the drill sequence until the 3.65mm final drill for 4.20mm implant.

The final drill was used to evaluate the accurate position and angulation of the preparation (

). A Self Tapping 4.20mm diameter 13mm length Tapered Self Thread Implant was inserted (

A cover screw was placed on the implant (

). The buccal bone defect and the space between the implant and socket were augmented with bone and were covered by a resorbable membrane (

The flap was sutured covering the entire augmentation (

). Figure 9 shows the site after healing.

Four months later the implant was exposed, positioning the flap buccally in order to achieve attached gingiva (

) was used to fabricate a crown by bonding porcelain to the zirconium taking into account that the crown creates the required gingival contour (

The crown was connected directly to the implant, the connecting screw was tightened and composite closed the top of the screw (

HI-TEC Implants has been developing, manufacturing and marketing an extensive range of dental implants and prosthetic elements since 1990. The company was founded by dental professionals with rich clinical experience and its commitment is to develop products that offer long term compatibility with implant dentistry. The goal is to continue to provide the most technologically advanced products to help dentists develop their practices in order to provide their patients with the most up-to-date treatment.

This case illustrates how using a 4.20 mm Tapered Self Thread from HI-TEC Implants is most suitable for achieving initial retention in the bone defect and as the wide platform has the closest fit to the socket.
