Why Oral Surgeons are Unique in the dental Profession

They are the surgical specialists of the dental profession. Their experience in general surgery, medicine, anesthesia and dentistry uniquely qualify them to diagnose, treat and manage conditions, injuries, and aesthetics aspects of the mouth, teeth, jaws and face. Maxillofacial surgeons are initially qualified in dentistry and have undergone further medical training.

Stem Cell Dental Implant

Dr. Lem is the only dental surgeon in the San Gabriel Valley who performs stem cell dental implant. A bone graft is necessary when the jaw bone is insufficient to support an implant.

Stem Cell grafting is the latest technology in helping bone to grow in deficient parts of the jaw. Stem cells are special cells that are found in the marrow of “flat” bones such as the hip or chest. The stem cells have the ability to multiply and become other tissue such as bone, cartilage, hair or skin. Stem cells are gathered by needle aspiration from the hipbone and placed against the jawbone. In four months, the stem cells “know” how to change into bone and make the region suitable for dental implants. The use of stem cells is revolutionary because the patient’s own live cells are used to create bone. 

Other dental offices mainly use freeze-dried powder bone (cow bone, artificial bone and other people's bone) but powders alone do not have any “live” cells and are less likely to result in bone.

State of the Art Dental Surgery Center

Our practice utilizes state-of-the-art technology and a modern facility with the most technologically advanced techniques and sterile equipment.

​Sterile Technique and Standards

Sterile technique is the effort taken to keep patients as free from micro-organisms as possible. It is a method used to prevent contamination of wounds and other susceptible sites by organisms that could cause infection. This can be achieved by ensuring that only sterile equipment and fluids are used during procedures. 

i-CAT Imaging

This revolutionary computer x-ray provides an in-office three-dimensional scan of the face and jaws. Cone beam technology has brought high-definition images with 90% less radiation compared to hospital scanners. 
The i-CAT improves care for: 

Implant surgery
TMJ disorders
Trauma
Sinus pathology
Jaw cysts or tumors
