The aim of this work is to underline the effectiveness of a protocol which involves the use of Platelet-rich plasma as a
grafting material in the implant rehabilitation.
The Authors included in the study protocol a cohort of 27 patients requiring
maxillary sinus lift, before implant-prosthetic rehabilitation, by using PRP in
combination with autogenous bone, anorganic bone material and organic bone
The treated patients were included in a follow-up plan, which established
clinical and radiological examinations on the day after surgery and six months
The success of the implant-prosthetic rehabilitation, defined as primary
stability and radiographic integration at the moment of the implant placement,
was of 100% (all 27 patients out of 27 included in the described protocol).

patient. It is possible to observe a great loss of alveolar bone in teeth 16
and 17.

maxillary arch. The yellow arrow indicates oroantral communication.

4 tubes containing 4 ml of PRP each.

Placement of two implants in teeth 16 and 17, subject to endosinusal
injection of liquid PRP. The implant placement was followed by PRP packing,
activated with Calcium Chloride + Bio-Oss.

peri-implant bone, six months after surgery.

Three-dimensional view that allows to examine the newly-formed bone in the
peri-implant area.

Orthopantomogram performed before surgery in a 45-year-old female patient
included in the protocol.

Post-surgery control Orthopantomogram in one of the patients included in the
protocol. Two implants were placed in teeth 15 and 16, subject to PRP
packing in the sinusal region.

Orthopantomogram performed six months after surgery. It is possible to
observe the presence of newly-formed bone in the peri-implant area.

seven with immediate load and one with delayed load (tooth 15).
