  • Dr. Callan was one of the first investigators utilizing bovine OsteoGraf/N distributed by CeraMed Corporation bone for the implantation within the jawbones of humans for reconstruction due to either cancer or diseased patients for guided bone regeneration.
  • Dr. Callan is also one of three investigators to utilize an artificial protein for the stimulation of bone growth within the upper and lower jaws of patients.
  • Dr. Callan was the first researcher of AlloDerm by grafting material for oral use, which is the most utilized soft tissue allograft material today. He pioneered the use of AlloDerm in dental surgery and is recognized as the world's foremost clinical expert with the material.
  • Dr. Callan is one of the pioneers in the development of fascia lata, distributed by LifeNet Tissue Bank, used as a membrane barrier material for guided bone regeneration.
  • Dr. Callan is one of the pioneers in the use of flex and bone putty grafton ostotech distributed by the American Red Cross for guided bone regeneration in preparation to support dental implants or to enhance the cosmetics of dental procedures.

Since 1991, Dr. Callan's office is and has been involved in teaching other surgical dentists bone grafting procedures and the proper technique of placing dental implants featuring the PerioSeal Implant System.

At his learning center, surgical techniques for success are emphasized including proper suturing (Ethicon Suture) and the proper use of materials. The placement of bone grafting material, membrane barriers, soft tissue grafts, and dental implants, involves more than just a technique. Proper instrumentation must be available (Salvin Dental Specialities) for the surgical dentist. Dr. Callan will review the instrumentation for each procedure in the learning center courses.

Maintenance of any patient's mouth is dependent upon personal (Sonicare) and professional care and utilizing the most advanced products on the market.
