Nilesh Parmar restores a patient’s smile using a dental implant.

This lovely man came to see me with a view to wanting to improve his entire smile. He was aware that he had neglected his teeth over the years, and wanted me to treat his entire mouth. He had previously been a smoker but had given up three years previously and medically he was fit and well.

 

Extra-oral findings were normal, with adequate oral hygiene in all quadrants. The patients BPE scores were 112/211. The patient admitted to not always brushing before he went to bed. He doesn’t floss and occasionally use mouthwash.

 

Intra-orally he had large edentulous area in the lower right and upper left areas of his mouth. This has made eating difficult as he has very few posterior contacts to masticate with. He has a crown with poor margins on the UL2 and various amalgam fillings which require replacing. The UR2 was heavily compromised, with little actual tooth tissue remaining.

 

The patient demands were to have a nicer, whiter smile, with some back teeth to eat with. We discussed various options and a combined restorative/perio/implant/cosmetic treatment plan was devised:

  •  Oral hygiene advice.
  •  Hygienist visit to re-enforce the above.
  •  Full volume CBCT scan of both jaws.
  •  Upper and lower study models and diagnostic wax ups.
  •  Upper and lower tooth whitening using Enlighten.
  •  Implant placement in the lower right edentulous area.
  •  Veneer preps on the upper central incisors.
  •  Crown preps on both lateral incisors.
  •  Replacement of all amalgam restorations with composite/Cerec restorations.
  •  Fitting of a three unit screw retained implant bridge in the lower right edentulous area.
  •  Fitting of E-Max Veneers and crowns on the upper incisors.
  •  Review appointment.
  •  Regular six monthly examinations and hygienist visits.

 

The patient was keen not to have too much of a ‘Hollywood smile’ and wanted a more natural masculine look. Numerous wax ups were made and edited until we were happy with the final prototypes. As with all smile makeover cases, the prototypes proved invaluable in reaffirming the proposed wax ups. The teeth were prepared and Luxatemp B1 prototypes were fabricated using the putty mask provided by the lab. The patient requested some minor contour changes, and this information was used when the final E-max restorations were made. The final restorations were made at the same time as the implant bridge in order to successfully manage the patient’s occlusion. The E-max restorations were bonded on with Vario Link II.

 

Implant Treatment

During the consultation process, the patient was not keen on having any form of internal or external sinus lift in order to place implants in the upper left edentulous area. Due to the limited height of alveolar bone, implant placement could not be carried out without some form of sinus floor manipulation. Due to this, it was decided to place implants in the lower right area, thereby restoring occlusion and masticatory function to one sides of the patient mouth at this time. A CBCT scan showed adequate bone height for the placement of two Astra TechTX Osseospeed implants.

 

The implants were placed under local anaesthetic using the Bien Air iChiropro surgical unit. This unit has the advantage of recording the entire implant procedure, and creating a graphical representation of the insertion torques of each implant placed. The implants achieved good primary stability, and healing abutments were placed at the time of surgery. Care was taken to maintain the limited keratinised mucosa around each healing abutment. The patient healed without incident, with fixture level impressions being taken three months after implant insertion. The implants were restored using a three unit fixed, screw retained bridge.

 

The patient was delighted with the final results and has been maintaining excellent oral hygiene since the work was begun. I am due to see him within three months to begin work on restoring the upper left edentulous area, as he has now consented to sinus floor manipulation. This lovely man, is a very

well motivated individual, and I believe his work has an excellent long-term prognosis.
