Implants are already recognized as essential to enhancing a patient’s quality of life. To ensure successful integration of the oral implant in the patient’s edentulous area, implants are now being developed in all different sizes, shapes, and widths, with various grooved surfaces and designs. This facilitates prosthetic restoration and the return of function. However, to achieve successful implant integration, aesthetic enhancement must be considered as an added possibility, along with phonetic improvement, when needed.

The practitioner’s goal is for a patient to be able to enjoy improved mastication as well as to speak with confidence. The patient is not only able to avoid a denture, which would hinder speaking and masticatory functions, but after successful oral implant integration, the patient also has a more youthful appearance and the potential for a new outlook on life. 

The success of oral implants depends on the acceptance of the implant and its integration with the bone. Certain considerations of the implant surgical site must first be made. Key questions include whether the bone of the implant surgical site can be optimized to ensure predictable integration and whether there is enough bone to support an implant. Another important question is whether there is enough bone to support and ensure predictable integration. Extractions are a major concern today.

After extraction, will there be enough bone to support the endosseous implant and its prosthetic restoration? Currently, it is generally accepted and advised to extract sooner rather than later as there is more bone available to support an implant. By waiting too long to extract, you risk ending up with less than the desired amount of bone. The more bone that is available, the more the implant surface contacts bone and, with all of today’s designs, the more predictable the osseous integration and success are.

This article emphasizes the preservation of the osseous walls of the extraction site during surgical extraction. There are now new proper surgical instruments with which the practitioner can, without strain or unnecessary physiologic positions, access and luxate in mesial and distal directions and remove the roots while preserving both the buccal and lingual walls of the osseous socket. This enables the retention of the existing blood supply, which will guide and aid the osseous regeneration of the future ideal osseous implant site.

In the history of dental extractions, removing the debilitated tooth out of the oral cavity as rapidly and as painlessly as possible has always been paramount. Based on the concept that the buccal bone is usually the thinnest zone of bone that retains the tooth and that it provides the least resistance, it is common practice after anesthesia to luxate in a bucco-lingual movement. Anatomically, the buccal plate of bone is usually much thinner than the palatal or lingual osseous plates.

However, this article will show that this method will not meet with optimal success. The easier extraction toward the buccal will actually result in the loss of more buccal bone. This is because healing depends on the available blood supply, primarily from the osseous walls of the extraction site. The constant pressure from the buccal-lingual luxation leads to ischemia in the remaining thin plate of buccal bone. The ischemia leads to further resorption and, therefore, the loss of buccal bone.

Upon healing, the area will have a depression in the buccal plate and occlusal resorption.

Problems resulting from the healed buccal depression include a buccal void, leading to poor oral hygiene, food retention, and an unaesthetic appearance. Another possible problematic result is the incorrect placement of the implant. The implant needs to be placed in adequate osseous support to succeed.

Since the implant must be placed where bone is, the implant placement will be lingual to the original tooth being replaced. This may result in a situation requiring a prosthesis that is similar to a buccal cantilever—ie, a prosthesis that is overextended buccally to ensure correct occlusion—but this would put undue stress on the implant. During extraction, our goal should be to preserve as much bone as possible by averting bone loss, especially of the buccal osseous plate. 

Mesial-distal Hoexter Luxators have been developed for use during extractions for the specific purpose of preserving as much bone as possible and have been utilized for many years. The Hoexter Luxators, distributed by Hu-Friedy, are designed to be used expressly in a mesial-distal motion to avoid any buccal pressure. The design of the instruments ensures that the practitioner maintains the correct angle of mesial or distal pressure on the root to be extracted with strain-free access and visibility, thus ensuring a successful and predictable result.

The Hoexter Luxator technique relies on the concept that it is easier to extract a single-root tooth than a multi-rooted one. After applying local anesthesia, the practitioner should remove the posterior tooth’s crown horizontally at its CEJ, thereby exposing the individual roots. At this time, the Hoexter Luxator should be placed in the desired location and moved with slight pressure in a mesial-distal direction. The root will become quite mobile and is easily removed.

There should be no pressure exerted on the buccal plate of bone during the technique. The resultant void will have its osseous walls intact. This can and will induce osseous regeneration and result in the desired healthy osseous support for the soon-to-be-inserted implant. This regenerated bone will include the buccal wall as well as the mesial, distal, and lingual and probably some interseptal bone. All the remaining osseous walls may be productive in guiding the positive regeneration of bone.

By using this technique and the Hoexter Luxator instruments, you will avoid the unhygienic buccal void; the unaesthetic, dark appearance of the buccal depression; and the resorptive depression of the buccal bone. You will also avoid the placement of an implant too lingually, which may cause future occlusal trauma. By successfully completing these steps with the Hoexter Luxator instruments, you will help to avoid bad oral hygiene and to overcome aesthetic and restorative challenges, thereby avoiding future occlusal trauma.
