1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

aimsThe purpose of this study is to assess the possibility and needs for bone augmentation in virtual planning and clinical treatment of prosthetically guided dental implants (PGI) following alveolar ridge preservation (ARP) in periodontally compromised molar extraction sites and to analyze the influencing factors. MATERIALS AND

methodsOne hundred forty three subjects with 191 molars were included. Radiographic data assessed baseline ridge height and width in variable sites. Virtual implant planning with 4.1/4.8 mm diameter, 8/10 mm length implants was performed using CBCT. The feasibility of simple implant placement and the need for augmentation during implant therapy were assessed. According to the medical records, the implant therapy modalities for sites that received dental implant treatment were also counted.

resultsResults of virtual implant planning showed that a few sites (6.81%) required staged augmentation for 4.1 × 8 mm and 4.8 × 8 mm implants, while 59.16% and 45.55% of the sites were possible for simple implant placement, respectively. For all cases clinically treated with implant therapy, 76.1% received simple implant placement, and 3.15% received staged augmentation. Implant treatment modalities were most influenced by location (maxillary/mandible) and the baseline buccal and lingual/palatal bone defects.

conclusionsPGI placement is possible in periodontally compromised molars following ARP, and only a few sites require complicated augmentation procedures. Location and baseline buccal and lingual/palatal bone defects are the influencing factors for implant treatment planning.
