Study summary

It is assumed that the reduction of the flap dimension could provide a reduction of surgical time, post surgical complications and patient's discomfort when compared with the traditional surgical approach.

Read the detailed description

16 edentulous patients in maxillary posterior area were treated with a bilateral sinus lift procedure. Once enrolled in the study impressions were realised and the radiographic stent prepared, with radio-opaque references fixed in the positions where the implants should be inserted. Pre-surgical CT scan was executed after placing the stent in its proper position in patient's mouth. If no surgical contra-indications were detected at CT evaluation, patients were involved in the study.

Sampling method
Probability sample

Study population

all the involved patients were edentulous in the maxillary posterior area , bilaterally, with a residual bone heigh of less then 4 mm; for this reason they required a surgical bone reconstruction for implant placement.

Inclusion criteria

  • patient edentulous in the maxillary posterior area on both left and right side
  • residual bone height in the maxillary premolar and molar region less than 4mm

Exclusion criteria

Exclusion Criteria:

  • history of systemic diseases that would contraindicate surgical treatment

Groups and cohorts

  • test side ( horizontal flap)

    Horizontal incision was realised in alveolar mucosa, in order to obtain the exposure of the lateral wall of the maxillary sinus, thus accessing the sinus cavity

    Procedure: flap

  • control side ( standard flap)

    Trapezoidal flap was realised, using a crestal incision and two deep vertical incisions extended in the fornix to expose the lateral wall of the maxillary sinus

    Procedure: flap

Interventions

  • Procedureflap

    after flap incision , the sinus cavity was opened and then the membrane raised up

    Also known as: surgical approach, Sinus augmentation

What researchers measure

Primary outcomes

  1. height of augmented bone obtained

    the height of the gained bone was recorded by using the control CT scan, realized after 6 months of follow up

    Time frame: 6 months

Secondary outcomes

  1. Duration of the surgery

    both total and partial times of different surgical steps were recorded

    Time frame: 1 day

  2. Post surgical patient's discomfort

    all patients were asked to fill out a VAS scale, graduated from 1 (minimal pain ) to 10 ( maximum pain)

    Time frame: 2 weeks
