Dr. Miski may recommend a regenerative procedure (bone graft) when the bone supporting your teeth has been destroyed. These procedures can reverse some of the damage by regenerating lost bone and/or gum tissues.
Periodontal bone regeneration procedures are referred to as guided tissue regeneration. The goal of a guided tissue regeneration procedure is to rebuild bone supporting the teeth as well as reestablishing the ligament attachment from the bone to the previously diseased root surface. This is usually performed by Dr. Miski by carefully exposing the roots of the teeth and their supporting bone and removing the disease-causing bacteria. Membranes (filters), bone grafts and/or tissue-stimulating proteins are placed in or on top of the defects in the jawbone to encourage your body’s natural ability to regenerate bone and tissue.
The membranes or tissue-stimulating proteins serve the purpose of allowing the slow growing bone to be isolated from the fast-growing soft tissues, thus guiding the what tissues are regenerated and where.

Bone grafting is a procedure which involves the replacement of missing bone with bone from another part of the patient’s body, bone from a donor or a substitute material. This surgical procedure is often necessary for patients undergoing dental restorations such as bridge work and dental implants. When a patient’s jawbone has either receded or become damaged, it will not provide sufficient support for implants. It is in such cases that bone grafting is necessary in order to provide a stable foundation for restorative work.
Reasons for Bone Loss
The stability and volume of the patient’s jawbone can be affected by a number of factors. The most common of such factors include:
Periodontal disease – Periodontal disease is the leading cause of bone loss in the oral cavity causing permanent damage to tissue and bone. When this disease affects the jawbone, it can ultimately lead to the loosening and loss of teeth as the support structures become progressively less stable. Dental injuries and infections — Trauma to the jawbone caused by physical injuries or oral infections can cause the jawbone to deteriorate and recede.
Tooth extractions — Tooth extractions typically lead to the loss of 40 to 60 percent of the surrounding bone over the three years following the extraction procedure.
Reasons for Bone Grafting
- Dental implants – Implants are the preferred replacement method for missing teeth because they restore full functionality to the mouth; however, implants need to be firmly anchored to the jawbone to be effective. If the jawbone lacks the necessary quality or quantity of bone, bone grafting can strengthen and thicken the implant site.
- Sinus lift – A sinus lift entails elevating the sinus membrane and grafting bone onto the sinus floor so that implants can be securely placed.
- Ridge augmentation – Ridges in the bone can occur due to trauma, injury, birth defects, or severe periodontal disease. The bone graft is used to fill in the ridge and make the jawbone a uniform shape.
- Nerve repositioning – If the inferior alveolar nerve requires movement to allow for the placement of implants, a bone grafting procedure may be required. The inferior alveolar nerve allows feeling and sensation in the lower chin and lip.
Types of Bone Grafts
There are several types of dental bone grafts. The following are the most common:
- Autogenous – This type of bone graft uses bone from the patient’s own body (often from another part of the jaw) to repair the damaged or deteriorated areas of the jawbone. Since the harvested bone comes from the patient’s own body, this method provides the most predictable and successful results and is therefore generally the preferred method.
- Allograft – Synthetic bone (manmade) can be created in the laboratory and used in the bone grafting procedure. Bone can also be obtained from a bone bank (cadaver bone).
- Xenograft – These grafts use cow bone which has been processed and sterilized to ensure that it is biocompatible.
When the human, cow or synthetic bone is added to the affected area it will fuse with the existing bone. While the entire process can take several months, bone grafting provides greater bone mass and therefore greater support for dental implants.
BOOK AN APPOINTMENT
Dr. Miski is a fantastic and extremely knowledgeable man, who understands that patients are not only concerned with a quality treatment, but also a qualitative understanding of the procedures and their reasons. Dr. Miski was always patient with his explanations and it is clear that it is very important to him that the patient understands. Aside from this, I was always comfortable with any dental procedures Dr. Miski conducted and trusted his judgement. I would highly recommend anyone to Dr. Miski purely due to the clarity he provides with every treatment.

I’ve been availing of Dr. Miski service for over 3years now and every experience is a joy. Dr. Miski is someone who really makes you feel he cares more about my teeth, more so than I do myself. He takes his time to explain all of your available options and no matter how many questions I ask of him, I never feel I’m burdening him. As someone with extreme sensitivity, never once have I ever felt any discomfort with any injection or procedure and can wholeheartedly say, my teeth have improved immensely since I started using the services of Dr. Miski. Unreservedly, I feel if the dentistry industry had more professionals like Dr. Miski, we all could benefit greatly.
The most beautiful and complete work seeing ever. Thank you Doctor.
I rarely found such attention to details in dental treatments and genuinely concern about my health… highly reliable expert since my first visit.
After a long road of dental work for Implants,the end result brought me to tears!I now know & can smile with confidence,due to the ultimate care that was given to me. Dr.Miski has become more of a friend and I trust him with anymore future dental work I will be having,I am so grateful.
