of two zygomatic implants and two paranasal implants is supporting a temporary bridge in the upper jaw
patient received 2 standard Nobel Biocare Nobel
Groovy RP implants of 13 mm and 2 zygomatic
Nobel Biocare implants of 47,5 mm each.
The 2 standard implants were placed in the left
and right paranasal area and the two zygomatic
implants were placed in de left and right zygomatic
buttress (Fig. 2).
In the lower jaw three BICON short 5 x 5 mm
implants were placed with a 3 mm internal well.
The zygomatic implants were placed according
to Stella’s technique7 using a channel through
which the implant installation was guided into
the maxillary sinus and further vertically into
146
the zygomatic buttress. The zygomatic implants
emerged closely to the crest of the alveolar ridge.
A temporary bridge was used to splint the
implants. After 12 months a final bridge restoration
was accomplished.
All implants integrated well, but the patient
continued to complain about the left zygomatic
implant. The complaints consisted of mucosal
inflammation adjacent to the abutments, chronic
discharge around the implant with bad taste.
In 2014, 15 months after placement of the implants
the zygomatic implant at the left zygomatic buttress
was removed and the oro-antral communication
