## Data Description

This dataset contains synthetic but realistic data for 10,000 dental implant patients, designed to predict implant survival over a 10-year period. The data is based on findings from recent scientific literature and includes 20 clinically significant features across patient demographics, clinical factors, implant characteristics, surgical factors, prosthetic factors, and outcome measures.

### Files

- **train.csv** - The training set, containing 7,000 patients with all 20 features and the target variable (`implant_survival_10y`).
- **test.csv** - The test set, containing 3,000 patients with the same 20 features but without the target variable.
- **sample_submission.csv** - A sample submission file in the correct format.
- **data_dictionary.md** - A detailed explanation of each feature in the dataset.

### What am I predicting?

You are predicting the probability that a dental implant will survive for 10 years. The target variable is `implant_survival_10y`, where `1` indicates survival and `0` indicates failure.

### Columns

Below is a detailed description of each column in the dataset. For more information, please refer to the `data_dictionary.md` file.

#### Patient-Related Factors
- **patient_id**: Unique identifier for each patient.
- **age**: Age of the patient at the time of implant placement.
- **gender**: Biological sex of the patient.
- **smoking_status**: Patient's smoking habits (Non-smoker, Former, Light, Heavy).
- **diabetes**: Presence of diabetes mellitus (0 = No, 1 = Yes).
- **vitamin_d_deficiency**: Vitamin D deficiency status (0 = No, 1 = Yes).

#### Clinical & Intraoral Factors
- **history_periodontitis**: Previous diagnosis of periodontal disease (0 = No, 1 = Yes).
- **bruxism**: Parafunctional grinding/clenching habit (0 = No, 1 = Yes).
- **oral_hygiene**: Patient's oral hygiene status (Good, Fair, Poor).
- **bone_quality**: Bone density classification (Type_1, Type_2, Type_3, Type_4).
- **jaw_location**: Location of implant placement (Maxilla, Mandible).

#### Implant-Related Factors
- **implant_length_mm**: Length of the implant in millimeters.
- **implant_diameter_mm**: Diameter of the implant in millimeters.
- **implant_surface**: Surface treatment type of the implant.

#### Surgical Factors
- **placement_timing**: Timing of implant placement after tooth extraction (Immediate, Early, Delayed).
- **insertion_torque_ncm**: Rotational force during placement in Newton-centimeters.
- **bone_augmentation**: Whether a bone graft or sinus lift was performed (0 = No, 1 = Yes).

#### Prosthetic Factors
- **loading_protocol**: Timing of prosthetic loading (Immediate, Early, Delayed).
- **restoration_type**: Type of prosthetic restoration (Single_Crown, Bridge, Overdenture).

#### Target Variable
- **implant_survival_10y**: **(TARGET)** Whether the implant survived for 10 years (0 = Failed, 1 = Survived).
