    mini-dental-intenroDue to their small diameter of 1.8mm – 2.4mm, MDI Implantology Mini Dental Implants are well suited for atrophied bone, often without the need for bone grafting.¹ Just one session might be enough to achieve long-term stabilisation of the denture¹ and positively impact your patient’s quality of life²

    Indications

    Functional principles

    Implants are placed through a small pilot hole which is prepared with a 1.1 mm drill. No full osteotomy! Usually, the average depth is one-third to one-half the threaded length of the implant.

  • Denture Stabilization in the Mandible, Dr. Winfried Walzer, Berlin, Germany.

    An edentulous male patient in his mid 40s came to our dental practice in Berlin since he had problems with his mandibular denture. He reported that he used denture adhesives for fixation. Nevertheless, functionality and stability of this prosthesis were insufficient – it was so loose that he even had difficulty chewing. Since he was not able to carry the financial burden of a conventional implant treatment and desired a quick, comfortable solution, it was decided to place four MDI Mini Dental Implants in the anterior mandible for denture stabilization. Since the old prosthesis was in poor condition, the dentist, dental technician and patient agreed that a new denture should be fabricated in the dental laboratory.
